Abstract
Protective coverings having metal nanoparticle agglomerates adhered thereto may be applied to a surface subject to infection. The protective coverings may comprise a base substrate, and metal nanoparticle agglomerates thereof adhered to the base substrate. The base substrate may be configured for attachment to the surface subject to infection. The surface subject to infection may be a mask or facial covering in a particular example. The base substrate may be conformable to the surface subject to infection and optionally include mechanical connectors and/or a contact adhesive upon at least one side thereof to promote surface attachment. The protective coverings may be applied to a contaminated touch surface as a temporary protective layer until disinfection has taken place. Alternately, the protective coverings may be used in routine infection control procedures. The protective coverings may be formed by applying a spray formulation comprising metal nanoparticle agglomerates upon a suitable base substrate.
