Abstract

Antimicrobial ceramic fibers based on a visible-light photocatalyst were made by templating on activated carbon glass fibers. Crystalline photocatalyst nanoparticles were grown in the interconnected nanopore system of the activated carbon. Removal of the carbon template in the subsequent calcination resulted in nanoporous ceramic fibers. When the fibers were immersed in suspensions of Pseudomonas aeruginosa under visible light illumination, the survival ratio of the cell was found to decrease with the time of exposure to the visible light. The kinetics of the bacterial killing was of the first order, reaching more than 40% bacterial killing in 30 min.
