Abstract

A coating composition that includes a mixture of a water-based coating polymer, an aqueous solution having silver-modified ceria nanoparticles (AgCNPs) and a weight percent loading less than about 3% weight/volume of the mixture, and a spore germination agent having a 0.1-1% weight/volume and the mixture configured for coating a surface.
