Polymer or polymer inks are used for reducing or eliminating harmful chemicals by offering a neutralizing chemical in the path of movement of the harmful chemicals. A neutralizing chemical responsive to the harmful chemical produces a harmless chemical as an output that is in the path of the harmful chemical and is opposite phase with the neutralizing chemical, preferably by 180 degrees, or is at least opposite in chemical compatibility to some extent. The neutralizing chemical can be suspended or combined with an inert carrier and preferably attenuates the harmful chemical concentration. The polymer ink can be applied to a media such as paper, (embossed or extruded) or polymer the same as paper but also in foam (open cell preferred) in order to obtain a decrease in the concentration of harmful gases. These forms can be utilized in air or liquid applications.

The present invention provides agents having efficacy against viruses, allergens, bacteria and odorants, materials including such agents, and methods for producing the agents. An agent according to an embodiment of the present invention includes titanium dioxide particles having low photocatalytic activity, and metal ions of at least one metal selected from gold, silver, platinum and copper that are adsorbed to the surface of the titanium dioxide particles. The agent may further include hydroxyapatite particles, and the metal ions may be adsorbed also to the surface of the hydroxyapatite. The metal ions may be at least partially present in the form of at least one of an oxide of the metal, a hydroxide of the metal, and the elemental metal.

In one aspect, the disclosure relates to antimicrobial films for use on high-touch surfaces in medical, commercial, and residential settings and methods of making the same. The films and coatings are robust and retain activity over time and are optimized to minimize diffusion time of virus particles as well as bacterial and fungal pathogens to the inactivating layers and/or particles in the films and coatings. In another aspect, the films and coatings are capable of inactivating multiple virus, bacteria, and fungi types, can be applied as sprayable coatings or adhesive backed films, or can be incorporated into fabrics. In still another aspect, the films and coatings can be formulated as transparent or can be a neutral color such as gray or white.

Metal nanoparticle agglomerates may aid in promoting infection control over an extended period of time when adhered to a touch or contact surface of personal protective equipment, such as gloves or garments. Gloves may comprise a body having one or more touch surfaces when worn, and metal nanoparticle agglomerates adhered to a material defining the one or more touch surfaces. The gloves may further comprise an identifying tag associated with the material. The identifying tag may be electronically identifiable, which may track, for example, how long the gloves have been in use, whether the gloves have been worn, conditions under which the gloves have been worn, and/or locations where the gloves have been worn. Other personal protective equipment and garments may similarly comprise metal nanoparticle agglomerates adhered to at least a portion of a material shaped for wear, optionally including an identifying tag associated with the material.
