Bacterial target-specific photocatalyst for the enhancement of antibacterial property to targets

A bacterial target-specific TiO2 photocatalyst was developed for the selective inactivation of bacteria in an aqueous environment. The bacterial specific antibody was conjugated with TiO2 and this TiO2-antibody composite achieved an antibacterial effect which targets specific bacteria with short UV exposure time and low particle concentration compared to raw TiO2 particles.
