Description

[Technical Field]

[0001] The present invention relates to a system for producing optical radiation to neutralize microorganisms.

[0002] The term "microorganism" refers to both bacteria and viruses, but also any pathogen such as fungi, algae, spores, toxins, proteins, parasites, etc.

[0003] In particular, the present invention also relates to the construction of a system configured to generate light radiation with technical properties (such as weight length), for example to inhibit microorganisms, such as bacteria and viruses, in particular SARS COV-coronavirus 2, through the modification of the genetic heritage of the microorganisms themselves.

[0004] The expression "modification of the genetic heritage" means the modification of at least one nucleic acid (DNA or RNA).

[0005] In general, the optical radiation produced by the system can be used to transfer an amount of energy to a microorganism that causes optical resonance in the microorganism itself.

[0006] Optical resonance induces irreversible physiological and morphological transformations in the microorganisms.

[0007] If the microorganism is a virus, specifically the SARS COV-2 coronavirus, the light radiation produced by the system causes irreversible damage to the genetic material of the SARS COV-2 coronavirus.

[0008] In the following description, reference is made to a system used to neutralize any microorganism comprising at least one first membrane.

[0009] In reality, a microorganism may have multiple membranes.

[0010] When a microorganism has a first membrane and a second membrane, the first membrane may be an outer membrane and the second membrane may be an inner membrane, i.e., the second membrane is disposed in an interior volume bounded by the first membrane.

[0011] In one example, when the organism is a virus with two membranes, the first membrane may be the pericapsid and the second membrane may be the capsid.

[0012] In a further example, when the organism is a virus having three membranes, the first membrane is the supercapsid, the second membrane is the pericapsid, and the third membrane is the capsid.

[0013] The same system can be used to the same advantage for different purposes.

[0014] In a first example, the system can be used to disinfect or sterilize any public or private environment intended to receive people, such as hospices, hospital wards, operating rooms, laboratories, cinemas, theatres, airplanes, trains, restaurants, bars, discos, gyms, swimming pools, etc.

[0015] In a second example, the system can be used to disinfect or sterilize any object, such as an instrument, product, or any fluid, such as a liquid or gas.

[0016] In a third example, the system can be used to sterilize food and beverages even in industrial production cycles (eg, sterilization of Salmonella, botulinum, etc.).

[0017] In further examples, the system may also be used in the medical field to reduce local viral load (e.g., present in the airways and / or alveoli of the respiratory system and / or in the patient's blood) or to treat dermatological changes or infected wounds. [Background technology]

[0018] Generally, microorganisms are organisms that are invisible to the human eye.

[0019] The microorganism comprises genetic material, in particular at least one nucleic acid, such as DNA and / or RNA.

[0020] Bacteria can be between 0.2 and 10 μm in size, and viruses between 0.015 and 0.25 μm.

[0021] As is known, viruses are microorganisms that can only be seen with an electron microscope.

[0022] Furthermore, viruses cannot sustain autonomous life and require the metabolic machinery of the cell, so they are forced to infect another organism in order to live and replicate.

[0023] It is also known that UV radiation can interact with nucleic acids, DNA and RNA, causing alterations in genetic makeup.

[0024] Thus, systems are known that are capable of emitting UV light radiation in order to modify the genetic heritage of microorganisms.

[0025] On the one hand, if the use of UV light radiation has the advantage of having a bactericidal effect on viruses or bacteria, on the other hand, the disadvantage of using UV light radiation is that UV light radiation also interacts with human DNA and RNA, causing harm to people who are directly affected by the light radiation, even if the intensity of the light radiation is reduced.

[0026] Furthermore, the time of exposure to photoradiation is long enough to result in a significant reduction in the viral / bacterial population.

[0027] Therefore, in the case of viruses such as coronaviruses, especially SARS-CoV-2, emitting UV light radiation against these viruses to human tissue would not only neutralize the virus, but also damage the human tissue with harmful tumor effects.

[0028] For this reason, namely due to the harmful oncogenic effects of UV light radiation on human tissue, the use of UV light radiation is prohibited in the presence of humans, and in particular its direct application to the human body.

[0029] The use of UV light radiation is restricted by strict limits: the maximum dose calculated over an 8-hour time interval is 30 J / m 2 is.

[0030] Furthermore, in the case of cleaning surfaces or objects made of solid or glassy materials, it must be taken into account that long UV irradiation times may be able to cause structural changes in the solid or glassy material.

[0031] Additional systems can generate light radiation to disinfect or sterilize or neutralize viruses / bacteria.

[0032] These systems comprise a light source having a wavelength such as a laser, emitting blue or red light radiation that, as verified experimentally but not theoretically, can cause alterations in the genetic heritage of microorganisms.

[0033] However, in addition to the laser, it is necessary to use photosensitizers or dyes or other substances that are not easy to find and therefore represent a limitation in the use of the system.

[0034] For example, when the laser is a pulsed laser at high frequencies (on the order of femtoseconds), the presence of a photosensitizer is not necessary to emit blue light.

[0035] However, the disadvantage is that such lasers are difficult to find and use.

[0036] Furthermore, the use of wavelengths in the visible or infrared spectrum to inhibit microorganisms is unknown. Summary of the Invention

[0037] The goal of the present invention is to overcome said disadvantages and to provide a system configured to emit optical radiation that, when directed at a person, is capable of neutralizing said microorganisms, in particular bacteria and viruses, more particularly SARS-COV2 coronavirus, on an object or on the tissues of the human body, without said tissues being damaged.

[0038] In particular, the system is designed to emit UV light radiation having wavelengths falling within a narrow band, which allows the UV light radiation to interact with microorganisms, causing an optical resonance that can neutralize the microorganisms.

[0039] On the one hand, the energy transfer from the light radiation to the microorganisms makes it possible to neutralize the microorganisms, and on the other hand, although this light radiation has a high power density inside the microorganisms because it is amplified inside the microorganisms due to the effect of the resonance phenomenon, this light radiation is not harmful to healthy tissues and therefore not harmful to people's health.

[0040] Object of the invention An object of the present invention is therefore a system for generating optical radiation for neutralizing microorganisms as claimed in claim 1.

[0041] Further embodiments are disclosed in the dependent claims.

[0042] The present invention will now be described, by way of example and not limitation, in accordance with embodiments thereof, with particular reference to the accompanying figures. [Brief explanation of the drawings]

[0044] Referring to Figure 1, a system for producing light radiation to neutralize microorganisms, particularly the SARS COV-2 coronavirus.

[0045] The system comprises: a light source 1 for emitting optical radiation; storage means 2 in which the following are stored: one or more unique identification codes, each associated with a respective microorganism; and at least one respective wavelength range associated with said microorganism; a logic control unit 3 connected to said light source 1 and to said storage means 2, selecting a wavelength range based on the microorganism to be neutralized; activating said light source 1 so that the optical radiation emitted by said light source 1 has a wavelength within said selected wavelength range, such that, when the system is in use, said optical radiation induces optical resonance in microorganisms, causing alteration of the genetic properties of said microorganisms; and a logic control unit 3 configured to perform the following.

[0046] Regarding the light source 1, the light source may be a UV lamp or a LED light source or a laser.

[0047] In particular, the wavelength ranges have been previously identified for each microorganism so as to induce optical resonance phenomena within the microorganism, as better disclosed below.

[0048] Multiple wavelength ranges can be associated with one or more microorganisms.

[0049] Wavelength values ​​in this wavelength range are chosen to induce optical resonance within the microorganism.

[0050] When multiple wavelength ranges are associated with one microorganism, the logic control unit 3 may be configured to select a wavelength range from among the multiple wavelength ranges.

[0051] Preferably, the logic control unit is configured to select a wavelength range whose wavelength value is greater than wavelength values ​​belonging to other wavelength ranges of said plurality of wavelengths.

[0052] In fact, light radiation with higher wavelength values ​​may belong to the visible spectrum rather than the ultraviolet spectrum.

[0053] Therefore, the light radiation emitted to the microorganisms is not harmful to human tissue.

[0054] It is preferred that the light source 1 is an LED light source, since an LED light source can emit light radiation with a narrower bandwidth and a more limited angle of emission than the light radiation emitted by a UV lamp.

[0055] Preferably, the bandwidth is 4 nm or less, and more preferably, the bandwidth is between 1 nm and 3 nm.

[0056] Advantageously, the use of narrow bandwidths, particularly between 1 and 3 nm, makes it possible to ensure, on the one hand, that the total dose of optical radiation to which the patient is exposed is below safety limits, and, on the other hand, that the microorganisms are irradiated with optical radiation having a wavelength that induces said optical resonance.

[0057] For light radiation emitted by an LED light source, the bandwidth and limited emission angle are useful for having light radiation that can have greater sterilizing or purifying capabilities.

[0058] In particular, the fact that optical radiation has a limited angle of emission allows it to maintain a high power density even at significant distances from the source.

[0059] Furthermore, LED light sources consume less energy than UV lamps to emit light radiation with the same intensity.

[0060] From the viewpoint of energy, it is more preferable that the light source 1 is a laser.

[0061] Therefore, lasers can be used to efficiently neutralize microorganisms belonging to a genus of viruses called the Coronaviridae family, such as the SARS-Cov-2 coronavirus.

[0062] The system may include at least one optical device 4 for focusing the optical radiation emitted by the light source 1 onto human tissue or onto an object to be sterilized or disinfected.

[0063] The optical device 4 is connected to the light source 1 through at least one first optical fiber.

[0064] The optical device 4 may include one or more lenses.

[0065] The one or more lenses may be converging to reduce the diameter of the optical radiation emitted by the light source 1 or diverging to increase the diameter of the optical radiation emitted by the light source 1 .

[0066] The system may include multiple optical devices, even if different from each other, depending on the type of light source.

[0067] The system may include filtering means 5 for selecting a predetermined bandwidth to obtain an optical resonance in the microorganism.

[0068] The filtering means is necessary when the light source is a UV lamp or an LED light source, but the presence of the filtering means is not necessary when the light source is a laser.

[0069] The filtering means 5 may include a bandpass filter.

[0070] In the disclosed embodiment, the optical device 4 is arranged between the light source 1 and the filtering means 5 .

[0071] However, the filtering means 5 can be located elsewhere.

[0072] For example, the filtering means 5 may be included in the optical device 4 without departing from the scope of the present invention.

[0073] In practice, the light source 1 may be capable of emitting optical radiation having a broadband spectrum comprising a plurality of wavelengths, and the filtering means 5 may comprise or consist of a bandpass filter configured to only allow wavelengths within the wavelength range to pass.

[0074] As already mentioned, the bandwidth of the wavelength range is preferably 4 nm or less, more preferably between 1 nm and 3 nm.

[0075] The system may include an optical probe 6 .

[0076] The optical probe 6 can be connected to the filtering means 5 if the filtering means 5 is included in the system, or to the optical device 4 if the filtering means 5 is not included in the system (e.g. when the light source is a laser).

[0077] In particular, the optical probe 6 can be connected to the filtering means 5 or to the optical device 4 via a second optical cable.

[0078] In a variant, the optical radiation 1 can be included in the optical probe 6 .

[0079] The optical probe may be a bronchoscopic probe, or a laryngeal probe, or a gastroesophageal probe, or an endoscopic probe.

[0080] Regardless of the type of probe described above, the optical probe 6 may be inserted during use in a patient, for example, within the airway, esophagus, hollow organs, and / or blood vessels.

[0081] Regardless of the presence of the optical probe 6 , the system may include a user interface module 7 .

[0082] The user interface module 7 may include a display device 7A for displaying the optical radiation and one or more parameters associated with the optical radiation, such as wavelength, optical power, duration of irradiation, etc.

[0083] The above-described system can be included in a dialysis machine.

[0084] Generally, a hemodialysis machine includes: at least one dialyzer filter, and - A fluid circuit connected to a first vascular access point of a patient and to a second vascular access point different from the first vascular access point (e.g., the two vascular access points may be located in an arteriovenous fistula).

[0085] Through the fluid circuit, a volume of blood is drawn from a first vascular access point and pumped towards the dialyzer filter.

[0086] The dialyzer filter filters the volume of blood before it is returned to the patient through the fluid circuit at a second vascular access point.

[0087] If a dialysis machine includes the system, the light source 1 is installed in the dialyzer filter so that the patient's blood is illuminated before, during or after filtration.

[0088] Below are some examples of genera of microorganisms and wavelengths of optical radiation (expressed in nanometers) that may be used to neutralize such microorganisms:

[0089] The wavelengths were identified through modeling of the microorganism and simulation of the system using numerical simulation software to solve one or more differential equations for the electromagnetic fields associated with the optical radiation received by the microorganism.

[0090] In other words, the numerical simulation simulates the propagation of optical radiation in a 3D model of at least one microorganism belonging to a given genus of microorganisms in an environment.

[0091] Each microorganism was modeled using the mean size.

[0092] The results of the numerical simulation are applicable to microorganisms with dimensions similar to those of the microbial subjects of the numerical simulation.

[0093] In particular, these dimensions may vary by a factor of ±5% relative to the size of the microorganisms being simulated.

[0094] Therefore, the results of the numerical simulations for approximately spherical microorganisms with an outer diameter equal to 100 nm can be applied to microorganisms with dimensions between 95 nm and 105 nm.

[0095] To model the behavior of microorganisms in air or water, the environment was modeled as a volume in which the physical properties of air or water were larger than the size of the associated microorganisms.

[0096] If we model a virus with an outer diameter equal to 100 nm, this environment would be, for example, 800 x 800 x 800 nm 3 It may be a cube with dimensions equal to

[0097] When the microorganism is a virus, it is particularly advantageous to model its behavior in water, since viruses are typically carried in fluids, such as saliva droplets.

[0098] Referring to Figure 5B, for 3D modeling of a virus belonging to the genus known as "Coronavirus family," specifically SARS-COV-2, such a virus was modeled using two concentric spherical elements, a first spherical element having a first diameter and a second spherical element having a second diameter smaller than the first diameter, to define four separate regions of the virus.

[0099] In particular, the shell of said first spherical element represents a first region of the virus associated with the pericapsid, said first diameter being between 95 nm and 105 nm, and in a particular case equal to 100 nm.

[0100] The shell of said second spherical element represents the second region of the virus associated with the capsid and has a diameter between 85.5 nm and 94.5 nm, and in a particular case a diameter equal to 90 nm.

[0101] Indeed, each shell is associated with a membrane of the microorganism and is assumed to have a thickness of 5 nm.

[0102] This assumption was also applied to further simulated viral membrane models, as better shown below.

[0103] The third region of the virus is between the shell of the first spherical element and the shell of the second spherical element, and the fourth region of the virus is inside the second spherical element and is associated with the genetic material, in this case viral RNA.

[0104] Furthermore, the first spherical element contains 100 protrusions, each with a length equal to 20 nm, to model the spikes of SARS-COV2.

[0105] These spikes were modeled as additional regions.

[0106] Other microorganisms can be modeled using 3D models other than those described above, particularly for viruses that contain several membranes, where the 3D models can provide a greater number of regions than those described above.

[0107] As mentioned above, the SARS-COV-2 virus is modeled through multiple concentric elements with spherical shapes.

[0108] However, a microorganism can be modeled with one or more elements having an ellipsoid shape, as explained below.

[0109] Each region of the virus is associated with a certain physical property, in particular a respective refractive index of electromagnetic radiation.

[0110] For SARS-COV2 and all other simulated viruses (explained better below), the refractive indices used are: - Refractive index of each virus membrane: 1.1+j0.001; - Refractive index of genetic material: 1.53+j1.1E-7; - Refractive index of virus matrix: 1.37+j1.1E-7, e; - Refractive index of spike protein: 1.47+j0.00274.

[0111] The differential equations were solved using the software for numerical simulation.

[0112] In the described embodiment, the software is finite element software, in particular Cosmol Multiphysics®, more particularly Cosmol Multiphysics® 5.5.

[0113] The Helmholtz equation for the electromagnetic field was solved in the frequency or time domain starting from closed boundary conditions to simulate the propagation of optical radiation of microorganisms inserted in the environment.

[0114] In particular, since the purpose of the numerical simulation is to observe the frequency behavior of microorganisms exposed to optical radiation having a predetermined wavelength, this equation was solved in the frequency domain to reduce the number of calculations required to process the data obtained from the numerical simulation.

[0115] For each simulation, the presence of an electromagnetic field source with a given wavelength and the fact that the radio waves were plane waves were used as boundary conditions.

[0116] The electromagnetic field source was placed at an infinite distance from the modeled microorganism, such that the wavefront impacting this microorganism was assumed to be locally flat.

[0117] In other words, the light source is positioned at an infinite distance from the microorganisms and emits light radiation having said predetermined wavelength.

[0118] Furthermore, the "perfectly matched layer" condition was used to model the behavior of the outer surface of the cube, which represents the environment into which the microorganisms are inserted.

[0119] The condition requires complete absorption of optical radiation incident on the outer surface of the cube at any angle of incidence.

[0120] The software for numerical simulations made it possible to carry out a frequency / wavelength scan of the light radiation to identify the frequency / wavelength at which the light intensity inside the microorganism had a relative maximum.

[0121] With reference to Figures 3 and 5 to 18, the results of simulations performed on viruses or bacteria belonging to the most common genera are shown below.

[0122] Figures 3, 5, 6, 7, 8, 9, 10A, 10B, 11, 12, 13, 14, 15A, 15B, 15C, 15D, 15E, 15F, 16, 17, and 18 show models of viruses or bacteria, respectively, that are used to simulate optical radiation incident on such viruses or bacteria.

[0123] Referring to the virus genus called "Coronavirus family", the SARS COV-2 virus shown in Figure 3 was simulated with the properties already described above.

[0124] For the virus, the table below shows the wavelength values ​​obtained in numerical simulations at which it was possible to obtain optical resonances, and the respective values ​​obtained from the ratio of the same wavelength values ​​to the diameter values ​​of the single membrane on which the virus is modeled. [Table 1]

[0125] The possible ranges of wavelengths centered around each wavelength value with a bandwidth equal to 4 nm are as follows: -first wavelength range: 158 nm to 162 nm; - second wavelength range: 111 nm to 115 nm; -Third wavelength range: 96nm~100nm.

[0126] In alternative embodiments, such a range may have a bandwidth between 1 nm and 3 nm.

[0127] A preferred wavelength value in the first wavelength range is 160 nm.

[0128] A preferred wavelength value in the second wavelength range is 113 nm.

[0129] A preferred wavelength value for the third wavelength range is 98 nm.

[0130] More preferably, the preferred wavelength value is 160 nm.

[0131] Each wavelength value corresponds to the peak of the simulated electromagnetic field Es (ie, calculated by numerical simulation) normalized with respect to the electromagnetic input field Ein.

[0132] FIG. 4 shows a portion of the simulated electromagnetic field Es normalized with respect to the input electromagnetic field Ein, in terms of wavelengths in the visible spectrum.

[0133] The normalized simulated electromagnetic field Es in FIG. 4 has multiple peaks, one at each wavelength value shown in the table above.

[0134] Below is a respective table showing, for each simulated virus / bacteria with given properties, one or more values, called wavelengths, at which the optical resonance is obtained, and for each wavelength value, at least one respective first value obtained from the ratio between the same wavelength value and the diameter of the first outer membrane at which the virus is modeled.

[0135] For membrane-bearing microorganisms, d is the diameter of the spherical element representing the membrane.

[0136] In the case of a microorganism having two membranes, d1 is the diameter of the first spherical element representing the first or outer membrane, and d2 is the diameter of the second spherical element representing the second membrane, located in the internal volume defined by the first membrane.

[0137] With further reference to the genus of viruses called "Coronavirus family," the MERS or SARS-COV virus shown in Figure 6 is modeled with the following characteristics: d = diameter of the spherical element representing the membrane = 180 nm; Number of spikes = 98, Spike length = 20 nm. [Table 2]

[0142] A preferred wavelength value in the third wavelength range is 128 nm.

[0143] The preferred wavelength value in the fourth wavelength range is 102 nm.

[0144] A preferred wavelength value in the fifth wavelength range is 86 nm.

[0145] A preferred wavelength value in the sixth wavelength range is 74 nm.

[0146] The preferred wavelength value in the seventh wavelength range is 58 nm.

[0147] More preferably, the preferred wavelength value is 174 nm.

[0148] With reference to the virus genus called "Reoviridae," the rotavirus shown in Figure 6 is modeled with the following characteristics: d1 = diameter of the spherical element representing the first membrane, called the supercapsid = 90 nm; d2 = diameter of the spherical element representing the second membrane called the pericapsid = 80 nm.

[0149] Furthermore, the virus has a capsid with a diameter of 30 nm.

[0150] However, the results obtained were not altered by omitting the capsid, and therefore the presence of the capsid was considered negligible for virus modeling. [Table 3]

[0151] The range of possible wavelengths, centered on each wavelength value with a bandwidth equal to 4 nm, is as follows: -first wavelength range: 112 nm to 116 nm; - second wavelength range: 66nm~70nm; -Third wavelength range: 52nm~56nm.

[0152] In alternative embodiments, such ranges may have bandwidths in the range of 1 nm and 3 nm.

[0153] The preferred wavelength value in the first wavelength range is 114 nm.

[0154] A preferred wavelength value in the second wavelength range is 68 nm.

[0155] A preferred wavelength value in the third wavelength range is 54 nm.

[0156] More preferably, the preferred wavelength value is 114 nm.

[0157] Referring to the virus genus called "Picornaviridae," the rhinovirus or aphthovirus or cardiovirus or hepatovirus or poliovirus shown in Figure 7 is modeled with the following characteristics: d = diameter of the spherical element associated with the membrane = 30 nm. [Table 4]

[0158] The range of possible wavelengths, centered on each wavelength value with a bandwidth equal to 4 nm, is as follows: First wavelength range: 44 nm to 48 nm, Second wavelength range: 30nm~34nm.

[0160] A preferred wavelength value in the first wavelength range is 46 nm.

[0161] A preferred wavelength value for the second wavelength range is 32 nm.

[0162] More preferably, the preferred wavelength value is 46 nm.

[0163] Referring to the genus of viruses called "Herpesviridae," the human cytomegalovirus shown in Figure 8 is modeled with the following characteristics: d = diameter of the spherical element representing the membrane = 200 nm; Number of spikes: 200, Length: 20nm. [Table 5]

[0164] The range of possible wavelengths, centered on each wavelength value with a bandwidth equal to 4 nm, is as follows: First wavelength range: 316 nm to 320 nm, Second wavelength range: 216 nm to 220 nm; Third wavelength range: 190nm~194nm; Fourth wavelength range: 165nm~169nm.
