[Technical field]
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 63 / 163,605, filed March 19, 2021, the entire disclosure of which is incorporated herein by reference. [Background technology]
[0002] Antiviral and antimicrobial compounds are chemical compounds that reduce or ameliorate the growth or development of viruses and microorganisms, respectively. The use of antiviral and antimicrobial compounds results in the death or cessation of growth of target microorganisms, including viruses and microorganisms.
[0003] Minimizing infections caused by pathogenic microorganisms is a major concern in many sectors, such as medical devices, hospital surfaces / furniture, dental restorations and surgical instruments, healthcare products and sanitary applications, water purification systems, textiles, food packaging and storage, industrial or household appliances, aviation, etc.
[0004] Infections are caused by touching, eating, drinking, or inhaling pathogen-containing materials. Generally, these infections are combated by drugs that target the pathogen. Of particular concern, however, are microorganisms that can quickly and easily mutate their genes to become resistant to these drugs, making their elimination difficult. For example, Staphylococcus aureus (S. aureus) generally colonizes human skin and mucous membranes without causing serious problems, but once the bacteria enters the body, it can cause a range of mild to life-threatening illnesses, including skin and wound infections, infectious eczema, abscess infections, heart valve infections or endocarditis, pneumonia, and bloodstream infections or bacteremia. Some S. aureus strains are resistant to methicillin and other β-lactam antibiotics - methicillin-resistant S. aureus (MRSA) - and require alternative types of antibiotics to treat them.

[Figure 1D] 1 is a graph showing the antimicrobial effect of embodiments of the polymer coating of the present disclosure against viruses and bacteria. [Diagram 2]1 is a scanning electron micrograph of an embodiment of a polymer coating of the present disclosure. Unlike nanosilver, the polymer coating of the present disclosure provides a smooth surface that enhances antimicrobial activity. Freeze-fracture SEM on high surface area carbon (>3000 m2 / g) shows a penetration depth in the range of 0.3-0.6 μm (300-600 nm). Area loadings equivalent to about 1 μm can provide a coherent coating, but coatings less than 1 μm can be easily formed on less porous surfaces. [Figure 3A] 1 is a graph of % transmission as a function of wavelength for an exemplary polymer coating of the present disclosure. [Figure 3B] FIG. 1 shows a thermogravimetric analysis (TGA) scan of an exemplary polymer coating of the present disclosure. [Figure 4] 1 is a table of embodiments of the polymer coating of the present disclosure. Water uptake can vary depending on the counterion. Chloride + low functionality variants are very hydrophobic, chloride or acetate + high functionality variants are hydrophilic, and nitrate + high functionality variants are in between. Hydrophilicity / hydrophobicity can provide differentiation of antibacterial and / or antiviral properties. For example, changes in hydrophilicity can result in changes in interactions with bacterial cell walls, viral envelopes, and affect polymer mobility.

Feline calicivirus (F-9) was used as a model for non-enveloped viruses such as respiratory viruses (e.g., Calicivirus family). Ultrathin films of approximately 0.75-1.5 μm were tested. [Figure 7] FIG. 1 shows a table of antimicrobial test results for embodiments of the polymeric coating of the present disclosure. [Figure 8] 1 is a table of kinetic analysis of antimicrobial test results for polymer coating embodiments of the present disclosure. Unprecedented activity for surface modifications was observed - half-lives of human coronavirus (229E), G+, and G- bacteria were demonstrated to be only less than 2.1 minutes - 4-5 log reduction to above detection limit within 30 minutes. All variants passed JIS / ISO protocols for antimicrobial activity (>2 log reduction in 24 hours). Acetic acid and 1.5 μm "thick" chloride films had better activity - ultra-thin coatings may increase hydrophobicity. [Figure 9] FIG. 1 is a schematic diagram of a drip flow reactor.

[0296] Example 1 Antimicrobial activity evaluation The overall antimicrobial test procedure is shown in Figure 5. This example was carried out on two different lots of polymer with different degrees of methylation (dm). The structures of the polymers are shown in Scheme 1 and Scheme 2 below. These are hereafter referred to as high (91%) dm and low (57%) dm. The iodide form of the polymer was dissolved at 2% by weight in 50:50 (v / v) methanol:acetone by heating at 40°C with stirring, and then precipitated in 1M aqueous solutions of the desired anions: sodium chloride, sodium nitrate and ammonium acetate, respectively. The precipitated anion-exchange polymer was filtered, washed with water and dried (80°C, 12 hours).
[0297] Dissolution for casting was performed by dissolving with stirring at 40°C. High dm polymers were dissolved in pure methanol at 0.7% by weight, and low dm polymers were dissolved in 88:12 (v / v) methanol:acetone. Untreated microscope slides (AmScope BS-50P, clear glass, ground edge, 1'' x 3'') were cleaned before use by sonicating in methanol for 30 min at room temperature. 1 mL aliquots of a given polymer solution were drop cast onto glass slides and allowed to dry overnight at room temperature in a fume hood.
[0298] Referring to Figure 2 (micrograph), Figure 3A (transmission), and Figure 3B (TGA), the polymer coated sample (high dm) was smooth, clear, and transparent. The polymer film properties are also shown in Figure 4.
[0299] [ka]
[0300] Referring to Figure 6 and Table 1 below, Samples 1, 2, 3, 4, and 5 represent polymers with polymer anions of nitrate, acetate, chloride (thin casting), chloride, and chloride (low degree of methylation), respectively. Two controls were also included; Sample C consisted of uncoated glass, and SBSC was an untreated internal control provided by Situ-Bioscience. Samples were provided in replicates of 3.
[0301] [Table 1]
[0302] Antibacterial Testing The ISO-22196 test method is designed to measure the antimicrobial properties of solid or hard surface treatment test samples incubated with selected microorganisms. The basis of the test method is that a bacterial inoculum in contact with the test sample is incubated, without drying, for a period of 24 hours. After this exposure, the inoculated bacteria is recovered and the concentration of the organisms is determined. Antimicrobial performance is determined by comparing the organisms recovered from the untreated material to those recovered from the treated material after the 24 hour incubation.
[0303] Antimicrobial performance is reported as both Log10 and % reduction compared to untreated control samples. Three time points were tested: 30 min, 6 hr, and 24 hr.
[0304] result All samples were tested in triplicate according to JIS Z 2801 and inoculated with Staphylococcus aureus (6538) and Escherichia coli (8739). All samples were plated in duplicate and tested for activity at 0.5 hours, 6 hours and 24 hours.
[0305] Referring to Figures 1B, 1D, and 7, Sample 1 showed a reduction in activity of 75.07% (0.6 Log10 reduction), 98.42% (1.8 Log10 reduction), and 99.80% (2.7 Log10 reduction) against Staphylococcus aureus, and 56.59% (0.4 Log10 reduction), 99.95% (3.3 Log10 reduction), and 99.68% (2.5 Log10 reduction) against Escherichia coli.
[0306] Sample 2 showed a reduction in activity of 99.00% (4.3 Log10 reduction), 99.99% (4.3 Log10 reduction) and 99.99% (2.74.6 Log10 reduction) against Staphylococcus aureus and 82.46% (0.8 Log10 reduction), >99.99% (5 Log10 reduction) and >99.99% (5.5 Log10 reduction) against E. coli.
[0307] Sample 3 showed a reduction in activity of 77.26% (0.6 Log10 reduction), 99.92% (3.1 Log10 reduction) and >99.99% (4.6 Log10 reduction) against Staphylococcus aureus and 40.50% (0.2 Log10 reduction), >99.99% (5.3 Log10 reduction) and >99.99% (5 Log10 reduction) against E. coli.
[0308] Sample 4 showed a reduction in activity of 98.72% (1.9 Log10 reduction), 99.99% (4.5 Log10 reduction), and >99.99% (4.6 Log10 reduction) against Staphylococcus aureus, and >99.99% (4.3 Log10 reduction), >99.99% (5.3 Log10 reduction), and >99.99% (5.5 Log10 reduction) against E. coli.
[0309] Sample 5 showed a 50.53% (0.3 Log10 reduction), 99.83% (2.8 Log10 reduction) and over 99.99% (4.6 Log10 reduction) reduction in activity against Staphylococcus aureus and 23.42% (0.1 Log10 reduction), 97.03% (1.5 Log10 reduction) and 98.93% (2 Log10 reduction) reduction in activity against E. coli.
[0310] Sample C showed a reduction in activity of 25.28% (0.1 Log10 reduction), 46.68% (0.3 Log10 reduction) and 69.24% (0.5 Log10 reduction) against Staphylococcus aureus and 9.58% (0 Log10 reduction), 0% (0 Log10 reduction) and 0% (0 Log10 reduction) against E. coli.
[0311] The internal control sample SBSC untreated control showed bacterial concentrations of 7.1E5 CFU / mL, 1.0E6 CFU / mL at 0 and 0.5 hours, respectively, and 7.7E5 CFU / mL, 1.4E6 CFU / mL, and 2.0E6 CFU / mL at 0, 0.5 and 24 hours, respectively, for Staphylococcus aureus.
[0312] The SBSC untreated control showed bacterial concentrations of 9.3E5 CFU / mL, 1.0E6 CFU / mL at 0 and 0.5 hours, respectively, and 7.0E5 CFU / mL, 1.1E7 CFU / mL, and 1.4E7 CFU / mL at 0, 6, and 24 hours, respectively, for E. coli.
[0313] Antiviral Testing ISO 21702 provides a test method for the quantitative evaluation of virucidal activity on plastics and other non-porous surfaces. The product to be tested is intended to be a treated antiviral product, which is tested against a specific virus. The basis of the test method is to incubate a virus inoculum in contact with the test sample for a period of 24 hours, without allowing it to dry. After this exposure, the inoculated virus is recovered and the concentration of infectious virus is determined. Antiviral performance is determined by comparing the virus recovered from untreated material with that recovered from treated material after 24 hours of incubation.
[0314] Antimicrobial performance is reported as both Log10 and % reduction compared to untreated control samples.
[0315] Tests were performed by contamination with the virus inoculum solution by incorporating 5% serum.
[0316] Results and Discussion Result: Log reduction rounded to one decimal place (e.g. 3.1).
[0317] All samples were tested according to ISO 21702 and inoculated with feline calicivirus (F-9) and human coronavirus (229E). All samples were tested for activity at 0.5 and 24 hours.
[0318] Cytotoxicity optimization was performed on sample 4 only.
[0319] Referring to Figures 1A, 1C, and 7, Sample 4 showed 0% (0 Log10 reduction) and 90% (1 Log10 reduction) reduction in activity against feline calicivirus (F-9) and greater than 99.99% (4.2 log10 reduction) and 99.99% (4 Log10 reduction) reduction in activity against human coronavirus (229E) at 0.5 hours and 24 hours, respectively.
[0320] Sample 5 showed a 78.5% (0.7 Log10 reduction) and 95.4% (1.3 Log10 reduction) reduction in activity against feline calicivirus (F-9) and a 99.7% (2.5 Log10 reduction) and 99% (2 Log10 reduction) reduction in activity against human coronavirus (229E) at 0.5 and 24 hours, respectively.
[0321] Sample C showed 0% (0 Log10 reduction) and 85.3% (0.8 Log10 reduction) reduction in activity against feline calicivirus (F-9) and 93.2% (1.2 Log10 reduction) and 95.4% (1.3 Log10 reduction) reduction in activity against human coronavirus (229E) at 0.5 and 24 hours, respectively.
[0322] The internal control samples, SBSC untreated controls, showed virus concentrations of 2.9E6log10TCID50 / sq cm, 2.9E6log10TCID50 / sq cm, and 6.1E6log10TCID50 / sq cm at 0, 0.5, and 24 hours, respectively, for feline calicivirus (F-9) and 6.1E5log10TCID50 / sq cm, 9.0E5TCID50 / sq cm, and 6.2E5Log10TCID50 / sq cm at 0, 0.5, and 24 hours, respectively, for human coronavirus (229E).
[0323] The ISO21702 intrinsic cytotoxicity optimization for sample 4 was negative.
[0324] Kinetic analysis and half-life data were also obtained and the results are shown in Figure 8.
[0325] Detailed antibacterial and antiviral tests and results. ISO22196: Antibacterial testing (Method for evaluating the antimicrobial activity of antimicrobial-treated plastic products, including intermediate products). It is not intended to be used to evaluate the efficacy and bacterial growth in plastics without antimicrobial treatment. Antimicrobial activity is determined by the following method: R = (Ut-U0) - (At-U0) = Ut-At (In the formula, R is antibacterial activity; U0 is the average common logarithm of the number of viable bacteria recovered from untreated test specimens immediately after inoculation (cells / cm2); Ut is the mean common logarithm of the number of viable bacteria recovered from untreated test specimens after 24 hours (cells / cm2); At is the mean common logarithm of the viable bacterial count recovered from treated test specimens after 24 hours (cells / cm2).
[0326] For general reference, the % reduction is also reported in the notes section for each sample result.
[0327] Legend CFU = colony forming units (typically stated per unit volume or surface area). CFU is determined by plating bacteria on a test sample according to a specified method and subsequently counting the resulting colonies.
[0328] Untreated Control (UTC) - Untreated control sample material used to demonstrate normal test performance, exhibiting robust microorganism growth.
[0329] Interval - represents the point or time at which a result value was determined; TO indicates that the result is from the earliest possible time from inoculation to collection of the inoculated sample (typically less than 5 minutes).
[0330] Result - The result is a measure of change or abundance. Result units often indicate the actual measurement relative to a control value depending on the method or test requirements.
[0331] Notes on changes to published test methods: Some references are made to "count agar plates" for testing method plating following neutralization and recovery of bacteria from the test sample. As a standard practice, counts are performed on appropriate plate media such as nutrient agar, tryptic soy agar, or as required by the particular organism being tested.
[0332] The published standard refers to incubation conditions of 35 ± 1 °C. Standard microbiological practice with other international methods is for incubations to occur at 37 ± 1 °C. Test conditions performed are at 37 ± 1 °C unless other temperature conditions are specified.
[0333] The expanded uncertainty of the test method for k=2 is for 95% confidence of Log10(0.136).
[0334] The uncertainty value for CFU is obtained by converting the CFU count (C1) to a Log10 value (Log10 C1); this result is multiplied by the expanded uncertainty (Log 10 C1 *EU), then subtracted from the Log10 value (Log C1 ± (Log10 C1 * EU)); convert it again by taking the real number (1×10^(Log C1±(Log10 C1 * EU)), upper and lower 95% confidence limits for CFU are obtained.
[0335] Defined method standards For ISO 22196, interlaboratory testing demonstrated results with a standard deviation of Log10(0.45) or approximately 1 / 2 log, which corresponds to a -mean ± 50% reduction.
[0336] Conditions for a valid test A test is considered valid if three conditions are met: If all conditions are not met, the test is not considered valid and the specimens should be retested.
[0337] The logarithm of the viable count recovered from the untreated test specimen immediately after inoculation must meet the following requirements: (L 最大 -L 最小 ) / (L 平均 )≦0.2 (In the formula, L 最大 is the common logarithm (i.e., logarithm to the base 10) of the maximum number of viable bacteria found on a specimen; L 最小 is the base 10 logarithm of the minimum number of viable bacteria found on a specimen; L 平均 is the base 10 logarithm of the average number of viable bacteria found on a specimen).
[0338] overview The ISO-22196 test method is designed to measure the antimicrobial properties of solid or hard surface treatment test samples incubated with selected microorganisms. The basis of the test method is that a bacterial inoculum in contact with the test sample is incubated, without drying, for a period of 24 hours. After this exposure, the inoculated bacteria is recovered and the concentration of the organisms is determined. Antimicrobial performance is determined by comparing the organisms recovered from the untreated material to those recovered from the treated material after the 24 hour incubation.
[0339] Antimicrobial performance is reported as both Log10 and % reduction compared to untreated control samples.
[0340] Three time points were tested: 30 min, 6 h and 24 h.
[0341] Results and Discussion Provide the results in a results data table
[0342] Test sample results Time point of outcome: (typically T0 or other time during the study) Unit of time: typically "hr" (hours) Result: Log reduction rounded to 1 decimal place (e.g. 3.1) Unit: Log decrease Limit of Detection (LOD): The LOD is entered in the results notes for each sample in which no bacteria were recovered.
[0343] JIS Z 2801-Antibacterial products-Testing of antimicrobial activity and effectiveness JIS Z 2801 specifies a method for the evaluation of antimicrobial activity of plastic products. It is a commonly used method to evaluate the antimicrobial properties of many material types, which can range from coated surfaces or those of monolithic composition. The basis of the test method is to incubate a microorganism inoculum in close contact with the test material on a flat horizontal surface for 24 hours. After this exposure, a sample of the inoculum is collected and the concentration of organisms is determined. Antimicrobial performance is determined by comparing the organisms recovered from the untreated inoculum-only test material after selected time points with the organisms recovered from the treated test material after selected time points. It is not intended to be used to evaluate efficacy and bacterial growth on plastics without antimicrobial treatment.
[0344] test Inoculum preparation After overnight incubation of the test bacteria, perform the transfer to the inoculum solution. Using a sterile inoculating loop, transfer one loop of the test bacteria into the prepared small volume of 1 / 500 NB. Make dilutions of this suspension with 1 / 500 NB as needed to establish the estimated bacterial concentration to obtain bacterial concentrations of SES CFU / mL to 2E6 CFU / mL with a target concentration of 1E6 CFU / mL.
[0345] Inoculation of test specimens The surface to be tested is the exposed outer surface of the product. · Pipette 0.2mL of the prepared test inoculum onto the test surface. · Cover the test inoculum with a 40mm x 40mm piece of film and gently press the film down so that the test inoculum spreads to the edges. · Ensure that the test inoculum does not leak past the edge of the film. After inoculating the specimen and applying the cover film, replace the lid of the Petri dish.
[0346] Incubation of inoculated test specimens The standard procedure for incubating the inoculated specimens is to incubate the Petri dishes containing the inoculated test specimens (including half of an untreated test specimen) at a temperature of (37±1)°C and a relative humidity of 90% or greater for (24±1) hours, unless otherwise specified.
[0347] Recovery of bacteria from test specimens. Immediately after inoculation, one-half of the untreated test specimens are treated by adding 5 mL of the appropriate neutralizing agent to the Petri dish containing the test specimen.
[0348] Test specimens after incubation After incubation, the remaining test specimens are processed. Viable bacteria recovered from the test specimens are immediately processed and counted.

[0356] ISO21702: Antiviral testing ISO 21702 provides a test method for the quantitative evaluation of virucidal activity on plastics and other non-porous surfaces. The products tested are intended to be treated antiviral products that are tested against a specific virus. The basis of the test method is to incubate a virus inoculum in contact with the test sample for a period of 24 hours, without allowing it to dry. After this exposure, the inoculated virus is recovered and the concentration of infectious virus is determined. Antiviral performance is determined by comparing the virus recovered from untreated material with that recovered from treated material after 24 hours of incubation.
[0357] Antimicrobial performance is reported as both Log10 and % reduction compared to untreated control samples.
[0358] Results and Discussion Provide the results in a results data table Tests were performed by contamination with the virus inoculum solution by incorporating 5% serum.
[0359] ISO21702 specifies a method for evaluating the virucidal activity of non-porous surfaces. Each product was tested using clean test conditions (no additional contamination). Unless otherwise stated, secondary effects of antimicrobial treatments, measured antimicrobial performance, or durability of measured activity are not covered by this standard. This standard is not intended to be used or referenced as a method for documenting or claiming antimicrobial performance unless indicated in a test report. Determination of product performance within a given environment can vary dramatically and must be specifically documented and then determined within the context of a specific project plan.
[0360] method Project - Special Biological Culture - Virus Cell culture of non-standard viruses used in a given test method. For each virus, employ the necessary media and culture conditions according to the standard requirements established by the laboratory.
[0361] ISO21702 - Determination of antiviral activity on plastic and other non-porous surfaces The ISO 21702 method is used to evaluate the virucidal efficacy of non-porous products. Tests can incorporate various exposure times, contamination, and virus types, as well as other variables, according to the test standard or the specific needs of the product. The most common test conditions employ standard method protocols that require 24 hours of exposure to the test material depending on the intended use of the product. The test virus is prepared prior to testing, followed by viral titer determination. The created inoculum is then utilized as the inoculum for exposing the test material to the virus.
[0362] ISO21702 Intrinsic Cytotoxicity Optimization Antiviral testing requires the use of host cells for growth and counting of virus concentration. The host cells must be viable and biologically intact to allow viral infection. Successful infection by the virus results in replication and eventual lysis and loss of the host cell. This process provides a means to measure the virus. Host cell cytotoxicity as a result of any chemical carryover from the test sample can affect the biological viability of the host cell and interfere with the processes necessary after exposing the cell to the virus. This interference is generally considered the intrinsic cytotoxicity of the test sample.
[0363] The test is performed by incubating the test sample with a neutralized recovery solution for 30 seconds, followed by exposing the host cells to eight concentrations of recovery solution. Intrinsic cytotoxicity is determined by the loss of cell culture viability.
[0364] test Inoculum preparation Prepare a suspension of known virus titer to a concentration of at least 1E6TCID50 / mL. Do not use virus passages greater than 10 passages from the original seed culture.
[0365] Experimental conditions After inoculation, the samples are incubated at 25°C ± 1°C (unless otherwise stated). Incubation is performed to prevent the inoculum from drying out while in contact with the test surface. After the incubation period, the virus is recovered in neutralizing medium and then diluted for culture.
[0366] Recovery of virus from test specimens Two time points are created for each test item, and washout of the inoculated samples is collected immediately after inoculation by placing the sample in a vial and adding 10 mL of the neutralizer solution of choice, followed by vortexing.
[0367] A second withdrawal is made after the intended incubation time (24 hours) after which the sample is placed into a vial containing 10 mL of neutralizing solution and vortexed. After test sample neutralization, aliquots of the sample are withdrawn and used to determine the infectious titer after each incubation period.

[0371] Sample preparation Each test material was prepared according to the requirements of the analytical method. Each test sample was prepared in replicates of 3 for each time point. Samples were cut into approximately 50 mm x 50 mm pieces as available. Sample variability was adjusted when necessary for standard testing, and notes regarding differences in sample characteristics were recorded in the report summary.
[0372] Ideally, the test sample is flat and non-hydrophobic to allow layering of the inoculum onto the sample surface.
[0373] calculation Perform end-point dilutions with the recovered virus inoculum using serial log10 dilution factors. Use TCIDSO (Spearman-Karber method; modified by MARamakrishnan) to determine the concentration of virus to be inoculated based on the result of the end-point dilution that results in the CTE of the host cells. This represents the end-point dilution (average) of the host cell monolayer that exhibits a CTE. Log10 50% endpoint dilution = -[(total number of CTE wells / total number of dilution replicates) + 0.5] x log dilution factor R = -[total CTE / number of replicates per dilution) + 0.5] x Log dilution factor R = log50% end point dilution Total CTE - the average logarithm of the number of viable viruses recovered from untreated test specimens immediately after inoculation (cells / cm2) Number of replicates per dilution - number of replicate wells inoculated at each dilution Log Dilution Factor - the dilution factor used for each dilution series (typically 10x or log10(10) = 1)
[0374] Antiviral activity value R = U(t24) - C(t24) R = antiviral activity value C(t24) = logarithmic average of three infectivity values after 24 hours from untreated material U(t24) = the common logarithm mean of the three infectivity values after the contact time (24 hours) with the treated (test) sample
[0375] statistical methods Replicate data are used for Spearman-Karber calculations and no additional statistical analysis is performed.

[0398] Example 4 Antifouling test Test polymer coupons are prepared by spraying a 5% by weight solution of the partially demethylated polymeric material of the present disclosure in mixed chloride / iodide form onto a glass slide to obtain a continuous film of a given thickness and a given mass loading. The coupons are then subjected to biofilm growth conditions and cell counts according to ASTM E2647-13, the Standard Test Method for Quantification of Pseudomonas aeruginosa Biofilms Grown Using a Drip Flow Biofilm Reactor with Low Shear and Continuous Flow, which is incorporated herein by reference in its entirety.
[0399] Specifically, ASTM E2647-13 specifies the operating parameters necessary to grow reproducible P. aeruginosa biofilms near the air / liquid interface in a reactor with a continuous flow of nutrients under low fluid shear conditions. The resulting biofilms do not represent one specific environment, but rather the generalized situation in which biofilms exist at the air / liquid interface under low fluid shear.
[0400] The test method uses a drip flow reactor. A drip flow reactor (DFR) is a plug flow reactor with laminar flow resulting in low fluid shear. This reactor is versatile and can also be used to grow and / or characterize biofilms of different species.
[0401] This test method describes how to sample and analyze viable cell biofilms. Biofilm population density is recorded as log colony forming units per surface area.
[0402] This test method is used to grow reproducible P. aeruginosa biofilms in a drip flow reactor. Biofilms are established by operating the reactor in batch mode (no nutrient flow) for 6 hours. Mature biofilms form while the reactor is operated for an additional 48 hours with a continuous flow of nutrients. During the continuous flow, the biofilm experiences very low shear caused by gravity flow of the medium dripping onto a surface set at a 10° angle. At the end of 54 hours, biofilm accumulation is quantified by removing coupons from the reactor channel, rinsing the coupons to remove planktonic cells, scraping the biofilm from the coupon surface to break up clumps, and then diluting and plating for viable cell counts.
[0403] The experimental setup is as shown in FIGS.
[0404] Water Purity - All references to water as a diluent or reagent are intended to mean distilled water or water of equivalent purity.
[0405] Culture medium: Bacterial liquid growth broth - Tryptic soy broth (TSB) 7 is recommended. Two different TSB concentrations are used in the test method: 3000 mg / L for inoculum and batch reactor operation and 270 mg / L for continuous flow reactor operation.
[0406] Bacterial plating medium - R2A agar7 is recommended.
[0407] Buffered Water - 0.0425 g / L KH2PO4 distilled water, filter-sterilized and 0.405 g / L MgCl·6H2O distilled water, filter-sterilized (prepared according to method 9050C.1a).
[0408] Pseudomonas aeruginosa (ATCC700888) is the organism used in this study. Isolated colonies from the R2A plates are aseptically removed and inoculated into 100 mL of sterile bacterial liquid growth broth (3000 mg TSB / L). The bacterial suspension is incubated for 20-24 hours at 35 ± 2 °C in an environmental shaker. The viable bacterial density should be equal to 108 CFU / mL and can be confirmed by serial dilution and plating.
[0409] procedure Batch phase: Place the cooling reactor in a horizontal position on the bench top. Aseptically add 15 mL of sterile 3000 mg TSB / L and 1 mL of inoculum to each channel. Tighten the lid of each channel with the nylon screw. Incubate the reactor system in a horizontal position at room temperature (2162 °C) for 6 hours in batch mode. Remove the foil from the outflow tube and attach the end to a waste carboy. Do not remove the clamp until the continuous flow phase.
[0410] Preparation for the continuous flow phase: Prepare continuous flow nutrient broth by adding sterile bacterial liquid growth medium to 20 L of sterile reagent grade water for a final concentration equal to 270 mg TSB / L (see 7.2.1). That is, dissolve the broth concentrate in a small volume of water and sterilize to prevent caramelization that may occur under the long sterilization times required for large volumes. Aseptically pour the concentrated medium into a carboy of sterile water to make a total of 20 L.
[0411] Adjust the angle of the reactor (Figure 11): Measure the length a (cm) of the reactor bottom. The angle (x) is 10°. Calculate y using the following formula: ya[sin(x)]) (In the formula, a = measured length of the reactor base (cm), x = angle (10°), and y = the difference between the length of b and the length of c (cm).
[0412] Determine the length of b and the length of c to get the required difference (y). Use the following formula: Y=bc (In the formula, b = measured length from the lower corner of the inlet end of the reactor base to the laboratory surface (cm); c = the measured length (cm) from the lower corner of the outlet end of the reactor bottom to the laboratory surface, and y = the difference between the length of b and the length of c (cm).
[0413] Remove the clamp on the outflow tube and attach the legs to the DFR. Adjust the legs of the reactor chamber so that the reactor chamber is tilted downwards at 10° until the required length (b and c) is achieved.
[0414] Continuous flow phase: Aseptically connect the inflow nutrient tube lines to the carboy containing the continuous flow nutrient broth. Feed each line through a pump head and connect a sterile needle to the end of each line. Aseptically attach the inflow tubing by inserting a sterile needle into the Mininert valve in the channel lid.
[0415] Turn on the pump and allow the medium to drip slowly onto the bacterial cells attached to the coupons. Pump a continuous flow of nutrients into the reactor through the pump set at a flow rate equal to 200 mL / hr (50 mL / hr per channel). The medium should flow downward from the inlet port to the outlet port. Regularly check the reactor for proper drainage and leakage. If problems occur, visually inspect the inlets and tubing for bacterial clogging. Run the reactor in CF mode for 48 hours.
[0416] Biofilm Sampling: Prepare sampling materials: vortexer, homogenizer, sterile beakers, sterile centrifuge tubes, culture tubes, pipettes, empty sterile Petri dishes, sterile spatula, and flame-sterilized stainless steel hemostats or forceps.
[0417] Loosen the screw on the channel lid with gloved hands and lift the channel lid. Aseptically remove one of the coupons by slowly lifting it with sterile hemostat. Place the coupon on a sterile Petri dish while carrying it to the sampling area. Hold the coupon with flame-sterilized hemostat, taking care not to disturb the attached biofilm. Rinse the coupon to remove planktonic cells: slowly immerse the coupon in a centrifuge tube containing 45 mL of sterile buffered water with fluid motion until the slide is completely covered. Immediately remove the slide by inverting, taking care not to agitate the liquid and the biofilm.
[0418] Remove biofilm from coupons: Using the flat end of a sterile spatula or scraper, scrape the biofilm-covered coupon surface downwards for approximately 15 seconds and place into a beaker containing 45 mL of sterile dilution buffer. Rinse the spatula or scraper by stirring in the beaker. Repeat the scraping and rinsing process 3-4 times to ensure complete coverage of the coupon surface.
[0419] Hold the coupon at a 60° angle over a sterile beaker and pipette 1 mL of sterile buffered water onto the top surface of the coupon. Repeat for a total of five rinses. The final volume in the beaker is 50 mL.
[0420] Analysis of biofilm samples: The scraped biofilm sample is homogenized in the beaker at 20,500±5000 r / min for 30 seconds. If more than one biofilm sample is taken, rinse the homogenizer probe between each new sample as follows: homogenize the dilution blank at 20,500±5000 r / min for 30 seconds, homogenize the tube containing 70% ethanol for 15 seconds, then remove the probe and leave it in the ethanol tube for 1 minute. Shake off any remaining ethanol from the probe, reattach the probe and homogenize the dilution blank for 30 seconds. Homogenize the third dilution blank and then the next sample beaker. Homogenizing the sample breaks down the biofilm clumps to form a homogenous cell suspension. Inadequate breakup can result in an underestimation of the viable cells present in the sample.
[0421] Using sterile culture tubes, perform serial 10-fold dilutions on the samples. Plate each dilution in duplicate for colony growth using an approved plating technique such as spread plating or spiral plating (Practice D5465). Incubate the plates at 35 ± 2 °C for 17-20 hours.
[0422] Cell counting: Count the appropriate number of colonies according to the plating method used. Calculate the arithmetic mean of the colonies counted on the two replicate plates. Calculate the log density of a coupon as follows; LOG 10 (CFU / cm 2 )=LOG 10 [(X / B)(V / A)(D)] (In the formula, X=average CFU, B = plated volume, V = volume scraped off, A = surface area scraped off, and D=dilution).
[0423] Calculate overall biofilm accumulation by calculating the average log density.
[0424] Example 4 Additional Polymer Performance Another exemplary polymer having the morphology shown in Scheme 3 was tested.

Equivalent ability to be cast as a film from low boiling and / or non-toxic solvents. Equivalent optical clarity, clarity, and transparency. Improved lot-to-lot charge density consistency. Reduced water uptake (or "water uptake to charge" ratio) for improved durability on surfaces exposed to water or frequently cleaned surfaces.
