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.Infection Control and Hospital Epidemiology. 2011;32(11):1130-1132.
