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.

- (24) lanthanum strontium cerium manganese iron copper oxide;
- (25) lanthanum manganese iron oxide;
- (26) cerium manganese oxide;
- or
- (27) a corresponding sulfide or oxysulfide of any of (1) to (26),
- on a carrier particle, wherein the carrier particle is an inert carrier particle.
A method of imparting anti-fouling character to a substrate surface, comprising applying to the substrate surface a coating which consists of or which comprises lanthanum strontium manganese oxide, wherein (a) the substrate surface is not a building structure, (b) the lanthanum strontium manganese oxide is not in a graphene composite that is spin coated on the substrate surface, and (c) when the lanthanum strontium manganese oxide is on a carrier particle, the carrier particle is an inert carrier particle.
