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.
Claims17
A method of disinfecting a fomite surface comprising applying lanthanum strontium manganese oxide to the fomite surface to impart antimicrobial surface character to the fomite surface, wherein the lanthanum strontium manganese oxide is applied at a mass ratio of at least 0.05% of total mass of fomite surface-forming material, wherein the lanthanum strontium manganese oxide is not in a graphene composite that is spin coated on the fomite surface, wherein the fomite surface is not a building structure, and wherein when the lanthanum strontium manganese oxide is on a particulate core material, the particulate core material is inorganic.
