Abstract
An antimicrobial material including a substrate and an antimicrobial mixed metal oxide, mixed metal sulfide, or mixed metal oxysulfide in and/or on the substrate is described, as well as antimicrobial coating materials and coatings formed therefrom. The antimicrobial material may be constituted in an antimicrobial surface of a surface-presenting substrate, to combat transmission and spread of microbial disease, e.g., disease mediated by microbial pathogens such as bacteria, viruses, and fungi. Antimicrobial mixed metal oxide, mixed metal sulfide, or mixed metal oxysulfide as described may be contacted with microorganisms to effect inactivation thereof.
Claims24
A method of inactivating microbial pathogens in and/or on a substrate, comprising:
- incorporating, in and/or on the substrate, (i) particles or (ii) a coating containing the particles, wherein the particles consist of antimicrobial mixed metal oxide, mixed metal sulfide, or mixed metal oxysulfide;
- and
- exposing the substrate with the incorporated antimicrobial mixed metal oxide, mixed metal sulfide, or mixed metal oxysulfide to air and water to cause the formation of reactive oxygen species including hydrogen peroxide on surfaces of the particles to inactivate the microbial pathogens.
