From: Nanostructured TiO2 anatase-rutile-carbon solid coating with visible light antimicrobial activity
Antimicrobial performance of NsARC. (a) Antimicrobial results showing 99.9% to 99.99% reduction in viable E coli bacteria on NsARC coated stainless steel after four hours. (b) Mechanisms of AMA: photonic light absorption by carbon and TiO2, diffusion of electrons and holes, surface reactions with water and oxygen to form ROS, diffusion of ROS through the aqueous environment, and damage of bacterium cell membrane.
