Efficacy of a Novel Light-Activated Antimicrobial Coating for Disinfecting Hospital Surfaces

Silicone polymers containing the light-activated antimicrobial agent methylene blue with or without gold nanoparticles were evaluated for their ability to reduce the microbial load on surfaces in a clinical environment. When irradiated with white light, polymers containing nanogold were more effective in this respect than those containing only methylene blue. Infect Control Hosp Epidemiol 2011; 32(11): 1130-1132
