[0034] The foregoing aspects and many associated advantages of the present invention will be more easily appreciated as they are better understood with reference to the detailed description that follows, when taken in conjunction with the accompanying drawings. Detailed description

[0035] Particulate pollution or particulate matter (PM) consists of solid and / or liquid particles in the air. Examples include dust, dirt, soot, smoke, and liquid droplets. This type of pollution can originate from primary sources that themselves form particles, such as wood-burning stoves and forest fires, as well as from secondary sources that emit gases which, in turn, form particles, such as power plants, coal fires, factories, vehicles, and the like. Often, these emissions contain PM in the form of fine particles (e.g., MP2.5) and / or coarse particles (e.g., MP10). Fine particles (e.g., MP2.5) can be considered particularly hazardous to health because they can penetrate the skin, lungs, blood, and / or other organs and cause health problems.In particular, exposure to MP2.5 has been associated with ischemic heart disease, stroke, COPD, diabetes mellitus, and lung cancer (Sang, S. et al. The global burden of disease attributable to ambient fine particulate matter in 204 countries and territories, 1990-2019: A systematic analysis of the Global Burden of Disease Study 2019. Ecotoxicol Environ Saf. 15 June 2022; 238:113588.).

[0036] There is a need for PM monitoring devices, systems, and methods that can be reliably implemented in a consumer or industrial setting for monitoring PM exposure over longer periods. This disclosure addresses these needs and other long-standing unmet needs in the art. POLLUTION DETECTION STAMPS

[0037] In one aspect, the disclosure proposes an article, for example, a pollution detection patch, for determining exposure to airborne particulate matter. In embodiments, the article may be operational for monitoring exposure to airborne particulate matter in combination with a computing device of the disclosure. The article may include a polymer, for example, a hydrophobic polymer, which adsorbs airborne particles onto it, causing discoloration of the polymer due to the adsorption of particulate matter onto the polymer. The article may further include a discoloration reference that contains one or more reference values ​​for optical comparison with a computing device or system. a degree of discoloration of the polymer with the reference. This optical comparison allows the determination of whether or not the article has been exposed to airborne particulate matter, and if so, to what degree, via a device or a calculation system.

[0038] In some embodiments, the article is intended for a binary determination, using a disclosure device or calculation system, of whether or not the article has been exposed to particulate matter (PM) in an environment (i.e., exposure to PM TRUE or FALSE). However, in some embodiments, the article may be decolorized to a degree of decolorization, and a plurality of decolorization references, for example, along a gradient, are configured for optical comparison with the decolorized polymer using a calculation device or system. In such embodiments, the optical comparison of the calculation device or system correlates a particular decolorization reference of the gradient with the degree of decolorization of the decolorized polymer to measure the article's exposure to airborne particulate matter using a calculation device or system.

[0039] By way of example, [Fig. 1] shows an example of a pollution detection patch, according to the disclosure, in an exploded perspective view. In the embodiment shown, a pollution detection patch 1 comprises a plurality of discoloration references 2 (i.e., is composed of individual discoloration references 5, 6, 7, 8) along a gradient, such that each discoloration reference corresponds to a degree of discoloration of the discolored polymer. For example, reference 5 corresponds to no or negligible exposure to MP; reference 6 corresponds to light exposure; reference 7 corresponds to intermediate exposure; and reference 8 corresponds to heavy exposure. The shade of the reference increases in opacity or darkening as the corresponding exposure levels are higher.In the embodiment shown, article 1 is circular, and the arrangement of the plurality of discoloration references 2 is a semicircle, with each discoloration reference (5, 6, 7, 8) being a sector of the semicircle. However, other article shapes and other arrangements of the plurality of discoloration references 2 can be implemented, according to other embodiments. In some embodiments, the plurality of discoloration references 2 can be laminated with a transparent polymer film or glass, for example.

[0040] In the embodiment shown, the plurality of discoloration references 2 is arranged on a semi-circular piece of suitable material, such as fabric, paper, polymer, plastic, wood, metal, or any combination thereof, or another suitable material; however, other shapes and / or materials may be used in other embodiments. In the embodiment shown, the plurality of discoloration references 2 is arranged so that the references are adjacent to each other in an arrangement where the gradient increases along the arrangement; however, the references (5, 6, 7, 8) can be arranged in any arrangement. In the embodiment shown, each reference (5, 6, 7, 8) contains an aperture (5a, 6a, 7a, 8a) through which it passes, so that surfaces positioned below the aperture are visible when viewed from above the article, as explained elsewhere herein. In this way, the references (5, 6, 7, 8) are more easily compared visually or optically with the polymer for the determination of an exposure level by a device or computing system.

[0041] In the embodiment shown, the patch 1 comprises a polymer layer 3, composed of an inert support 10 and a polymer 11; in other embodiments, the inert support 10 is coated with a dispersion of a pollutant-attracting polymer, as described elsewhere herein. The inert support 10 may be non-reactive with PM; however, the polymer 11 is reactive with PM in that it adsorbs PM onto itself, resulting in decolorization of the polymer 11 and functionality of the patch in detecting and / or quantifying exposure levels to airborne PM in the environment. In some embodiments, the polymer 11 is deposited on one half of a circular inert disc-shaped support 10, such that one half of the inert support 10 does not include the polymer on it, and the other half of the inert support 11 does include the polymer on it.However, in some embodiments, a larger part of the inert support 10, for example, the entire inert support 10, can receive the polymer 11 deposited on it for complete coverage of the upper surface of the polymer layer 3 with the polymer 11.

[0042] In the embodiment shown, article 1 further includes a fastening portion 4 configured for attaching article 1 to a surface. The fastening portion 4 may include, for example, an adhesive tape, a magnetic layer for attaching the stamp to metallic surfaces such as cars or other objects, a hook-and-loop fastener, or some other structure on a base of the fastening portion 4. The fastening portion 4 may include an adhesive 12 on a top surface of the fastening portion 4 for attaching the polymer layer 3 to it.

[0043] In some embodiments, the attachment portion 4 can be configured to suspend Article 1 from a surface or another article, or from the body of an individual wearing Article 1. In cases where a person is wearing Article 1, Article 1 can function as a kind of "dosimeter" to monitor the person's exposure to MP. This wearable "exposome monitor" can monitor individual exposure and serve as an early warning system for potentially harmful exposure levels, allowing the individual to mitigate their exposure. to potentially harmful pollution (e.g., "exposome") by adjusting one's location, behavior, or routine, or by implementing other protective actions such as the application of protective materials, substances, or personal protective equipment (PPE) to protect the individual against potential health problems due to exposure to PM. In some embodiments, the stamp can be used as an indicator of when and / or where respirators and / or eye protection or other protective equipment should be worn. In some embodiments, the stamp itself can be used as an indicator of when and / or where a filter, such as a respirator or other PM filter, is worn or clogged and needs to be serviced, cleaned, or replaced; for example, the stamp 1 can be attached to or integrated into a respirator, such as an N95 respirator, or similar.Furthermore, in industrial environments, for example, the accumulation of airborne PM can be an indicator of actual or potential equipment failure; in such cases, stamp 1 can be used to warn operators of an impending failure or a need for equipment maintenance.

[0044] In the embodiment shown, a central hinge comprises an upper pin 9a, which extends through the polymer pinhole 9b and the pinhole of the fastening portion 9c to secure the plurality of discoloration references 2 to the polymer layer 3 and the fastening portion 4 to form an assembled state of article 1 for use. The central hinge (91, 9b, 9c) allows rotation of the plurality of discoloration references 2 relative to the polymer layer 3, as described elsewhere herein, for easier visual comparison of the references (5, 6, 7, 8) with the discoloration of polymer 11.

[0045] In some embodiments, the references in the plurality of discoloration references (5, 6, 7, 8) correspond to qualitative levels of exposure to PM as calculated and / or communicated by a calculating device or system. For example, in at least some situations, it may suffice for the PM exposure level to be indicated by the calculating device or system as "slight," "intermediate," or "significant," as appropriate. However, in other situations, the references in the plurality of discoloration references 2 (i.e., 5, 6, 7, 8) correspond to defined quantitative levels of exposure to PM. An example of a defined exposure level might include exposure to a particular concentration of airborne PM, optionally for a specific period of time.In some embodiments, the references of the plurality of decolorization references can be chosen or calibrated based on the performance of a particular polymer over a range of defined quantitative exposure levels to MP. In this way, the coloration or tint of a . A given discolored polymer state can be correlated with a particular reference for determining at least an approximate exposure level as indicated by that reference. Suppose, for example, that reference 6 corresponds to a quantification of MP exposure of X. If the polymer in the article discolors so that it resembles at least approximately reference 6, then it can be stated that a quantification of MP exposure in one or more environments in which the article is placed is at least approximately X. In this way, the article can be configured for qualitative and / or quantitative use and can be used in any of various scenarios, including personal, industrial, and other uses.

[0046] Referring now to [Fig. 2], a top view of the example pollution detection patch 1 is shown in an assembled state and not exposed to particulate pollution. The polymer is in an uncolored state 1la, and optically corresponds to the reference 5, i.e., the negative control reference. In the embodiment shown, the uncolored state 1la of the polymer is a brilliant white. As shown in [Fig. 3], after exposure to a degree of particulate pollution such that one polymer of the patch is colorless, the polymer is in a colorless state 11b. In the embodiment shown, the decolorized state 11b corresponds optically to the reference 6, so that a visual aspect of the decolorization reference 6 agrees at least partially with a visual aspect of the decolorized polymer 11b for the determination of whether or not the article has been exposed to airborne particulate matter, and if so, to what degree.

[0047] Referring now to [Fig. 4], a top view of the example pollution detection stamp 1 is shown after exposure to particulate pollution, with a decolorization reference 6 configured for optical comparison. This reference is moved or rotated for comparison with the decolorized polymer 11b by a computing device or system. In the embodiment shown, the plurality of decolorization references (5, 6, 7, 8) are rotated 90 degrees so that the decolorization reference 6 overlaps the polymer when the polymer is in the decolorized state 11b. In this configuration, the decolorized state 11b is visible through the aperture of the reference 6, for easier visual comparison of the reference 6 with the decolorized state 11b.In the example shown, the bleached state 11b corresponds at least approximately to reference 6, for example, based on a grayscale color and / or tone, brightness, chromaticity, and / or saturation. The bleached state 11b, and other bleached states of the polymer, may appear as reductions in brightness from the default color in bright white, for example. The determined exposure can be graduated, by [the relevant factor]. for example, in the form of a score from 1 to 10, where 1 corresponds to lower exposure and 10 to higher exposure to MP, according to embodiments.

[0048] In some embodiments, the pollution detection patch can be implemented as, or incorporated into, any form factor as required. Examples of form factors include a disposable patch, a reusable patch, a washable patch, a bracelet, a ring, a necklace, or other wearable form factor. In some embodiments, the patch can be attached to a vehicle, a house or other structure, equipment monitoring systems, manufacturing or machining systems, and the like.

[0049] In some embodiments, the polymer used to make the patch is hydrophobic and can attract airborne pollutants such as dust, carbon soot, MP2,5, and others. In some embodiments, a polymer produced by MYCELX® may be used as the polymer for a patch or disclosure item; however, any suitable polymer or other material may be used depending on its effectiveness. Examples of MYCELX® polymer compositions for making a polymer for a patch or disclosure item may include, by way of non-limiting example, one or more compositions or one or more polymers disclosed in U.S. Patent No. 5,746,925, one or more compositions or one or more polymers disclosed in U.S. Patent No. 5,437,793, and / or one or more compositions or one or more polymers disclosed in U.S. Patent No. 5,698,139.

[0050] In some embodiments, a polymer composition of the disclosure may be produced by chemical reaction (e.g., crosslinking) of linseed oil with isobutyl methacrylate, and the product diluted with a suitable solvent, such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The composition formed by the thermal reaction of linseed oil with the isobutyl methacrylate polymer is a flexible resinous product which, when diluted with the solvent, gives rise to a mixture that can be sprayed onto a surface, such as the inert support 10 of the disclosure stamp. In some embodiments, a polymer of the disclosure article may be produced from methacrylate polymers and any of various natural animal and vegetable oils.The oil and polymer can be reacted in a thermal reaction that does not appear to be sensitive to the atmosphere under which the reaction is carried out, i.e., whether it is an inert, oxidizing, or reducing atmosphere. Compositions with an oil / polymer ratio ranging from approximately 3:1 to 1:1 can be used, resulting in polymers with physical properties ranging from flexible to hard, and from elastomeric to brittle in nature, depending on the oil / polymer ratio and the choice of polymer and / or oil used.

[0051] In some embodiments, a polymer composition can be applied to the inert support 10 by reducing the viscosity of the polymer composition and depositing it onto the inert support 10, which may be porous. Since the viscosity of MYCELX® polymer compositions at room temperature is very high (for example, approximately 700 to 800 Pa*s), in some embodiments, a deposition process for depositing a polymer composition onto an inert support 10 includes reducing the viscosity of a polymer composition by heating or dissolving it in a solution, and then depositing the polymer composition with reduced viscosity onto an inert support 10.

[0052] As a first example of depositing a polymer composition onto an inert support 10, a first step includes mixing the polymer composition in a caprylic / capric triglyceride at any concentration, from 0 to 100%, to produce a polymer composition mixture; a second step includes immersing the stamp (e.g., the inert support 10, which may include cellulose, for example) in the polymer composition mixture for 30 minutes; and a third step includes removing the inert support 10 from the polymer composition mixture and drying the inert support 10, optionally at an elevated temperature, for a period (e.g., overnight).

[0053] As a second example of depositing a polymer composition onto an inert support 10, a first step includes mixing the polymer composition with isododecane at any concentration, from 0 to 100%, preferably from 20 to 100%, to produce a polymer composition mixture; a second step includes immersing the stamp (e.g., the inert support 10, which may include cellulose, for example) in the polymer composition mixture for 30 minutes; and a third step includes removing the inert support 10 from the polymer composition mixture and drying the inert support 10, optionally at an elevated temperature, for a period (e.g., overnight). REQUIREMENTS AND METHODS

[0054] In other aspects, the disclosure proposes kits that include one or more of the disclosure's patches. Examples of kit embodiments include a pollution detection patch, optionally in combination with instructional materials, for example. The kits may be supplied and / or used as standalone units, or may be combined with other products or kits for bundled offerings. An example of a bundled kit includes one or more pollution detection patches and one or more skincare products, for example, to mitigate adverse skin health problems that might result from exposure to pollution, such as MP.

[0055] In other aspects, the disclosure proposes methods for managing or mitigating the risk due to exposure to particulate matter, optionally in combination with one or more other pollutants or environmental stressors. As shown in [Fig. 5], an example of a method 13 for mitigating the risk due to exposure to particulate matter may use an example of a pollution detection patch according to the disclosure. In the embodiment shown, the risk mitigation method 13 includes step 14: providing a pollution detection patch, in which a patch is provided to a person, a group of people, or an organization. In step 15, which may be optional, the pollution detection patch may be attached to a surface. In step 16, the pollution detection patch is exposed to particulate pollution, resulting in discoloration of the patch's polymer, as described elsewhere herein.In step 17, a device or calculation system is used, for example, by an individual operator, to scan the pollution detection patch. The device or system calculates the patch's PM exposure level based on an optical comparison, mediated by the imaging device or system, of one or more discoloration references with the image of the discolored polymer. In step 18, the individual receives the particulate pollution exposure level and / or action and / or product recommendations from the calculation device or system. In step 19, the individual makes a change to adjust their exposome—the range of potentially harmful environmental exposures to which an individual or group of individuals is exposed (including PM exposure)—so that the individual or group of individuals has a lower risk of adverse health problems due to their exposome.Examples of adjustments may include changing a travel or transportation itinerary, staying indoors for a specified period of time, wearing a respirator mask, applying a cosmetic composition to the skin or another part of the body, taking medication, or other actions. COMPUTING DEVICES, SYSTEMS AND METHODS

[0056] In various aspects, the disclosure proposes a computing device configured for determining exposure to airborne particulate matter. The computing device includes circuitry configured to capture an image of a pollution detection item (e.g., the pollution detection patch 1 in Figures 1 to 4). The image of the patch includes imaging of a discoloration reference and imaging of a polymer configured to adsorb airborne particles onto it, causing the polymer to transform into a discolored polymer, as described herein. The computing device further includes circuitry configured to compare the discoloration reference to the discolored polymer. For optical comparison, this allows the calculation device to determine, for example, whether or not the pollution detection device is exposed to airborne particulate matter. As such, in some embodiments, the calculation device further includes circuitry configured to determine whether the pollution detection device is exposed to airborne particulate matter based on optical comparison (i.e., a binary determination; YES or NO). In some embodiments, the calculation device further includes circuitry configured to determine the level of exposure of the pollution detection device to airborne particulate matter based on optical comparison (i.e., a measurement determination; exposure level).

[0057] Non-limiting examples of user interfaces are shown in Figures 7A to 7K.In embodiments, the computing device further includes circuitry configured to display, via a user interface of the computing device, health knowledge or findings, historical exposome trends, statistical information related to an exposome, environmental factors such as UV radiation, pollution, humidity, pollen levels, skincare routine(s) used or suggested for use, lifestyle programs or trends such as exercise patterns or diet or sleep patterns, weather information or forecasts, information on future exposomes predicted due to environmental and lifestyle factors, qualitative or quantitative information on exposure, perceived or calculated or actual aging rate, resilience trends or the like, or any combination thereof.In some embodiments, the calculation device further includes circuitry configured to display, via a user interface of the calculation device, a recommendation for action and / or product based on an exposure level to airborne particulate matter of the pollution detection article as determined on the basis of optical comparison.

[0058] In some embodiments, the circuitry of the computing device is configured for image recognition detection of the discoloration reference and the discolored polymer based on an arrangement of the pollution detection item, which may be, for example, a (known or expected) position of the discoloration reference relative to a position of the discolored polymer, or may be predefined based on an arrangement of the discoloration reference and the discolored polymer on the pollution detection item, for example. In at least some embodiments, the circuitry of the computing device is configured for detection by image recognition of the discoloration reference and the discolored polymer independently of the arrangement of the pollution detection article.

[0059] In various aspects, the disclosure proposes a computing device configured for measuring exposure to airborne particulate matter. The computing device includes circuitry configured to capture an image of a pollution-sensing article. The image includes imaging of a plurality of discoloration references along a gradient and imaging of a polymer of the pollution-sensing article. The polymer is configured to adsorb airborne particles onto it, causing the polymer to transform into a discolored polymer, as described herein. The circuitry of the computing device is configured to compare the plurality of discoloration references to the discolored polymer for optical comparison, thereby enabling the measurement of the pollution-sensing article's exposure to airborne particulate matter.In embodiments, each decolorization reference corresponds to a level of exposure to airborne particulate matter that is based at least in part on a concentration of airborne particulate matter in an environment.

[0060] Figure 6 shows an example of a method for calculating an exposure level and generating a recommendation to mitigate the risk due to exposure to particulate matter, as can be performed with a calculation device according to the disclosure. The method 20 comprises, in step 21, capturing an image of a pollution detection stamp showing a reference color and a polymer decolorization; in step 22, comparing the reference color to the polymer decolorization for an optical comparison; in step 23, calculating a level of exposure to particulate pollution based on the optical comparison; and in step 24, displaying an action and / or product recommendation via a user interface of the calculation device.

[0061] In some embodiments, the optical comparison includes calculating, based on image imaging, a degree of discoloration of the discolored polymer, and calculating a degree of discoloration of the plurality of discoloration references that is associated with the degree of discoloration of the discolored polymer. These calculations allow the measurement of the exposure of the pollution detection article to airborne particulate matter, for example, by the calculation device. In some embodiments, the optical comparison includes calculating, based on image imaging, a plurality of degrees of discoloration of the plurality of discoloration references and calculating a standard curve thereon configured for calculating the degree of discoloration of the plurality of discoloration references, for example, by the calculation device.

[0062] In some embodiments, the calculation device includes circuitry configured to display, via a user interface, a recommendation for action and / or product based on the level of exposure to airborne particulate matter of the pollution detection device as determined based on optical comparison, as described herein. In some embodiments, the recommendation is further based on a historical level of exposure to airborne particulate matter of the pollution detection device and / or a historical level of exposure to airborne particulate matter of an individual, for example.

[0063] In some embodiments, the computing device's circuitry is configurable with a processor and processor-executable instructions stored on a machine-readable, non-transient medium of the computing device, by way of non-limiting example, but other approaches to configuring the computing device's circuitry may be implemented in other embodiments. In some embodiments, the computing device includes a processor for executing instructions stored on a machine-readable, non-transient medium, to enable the processor to perform all or part of a disclosure method or process.
