Photocatalytic antibacterial effects are maintained on resin-based TiO2 nanocomposites after cessation of UV irradiation.
Photocatalysis induced by TiO2 and UV light constitutes a decontamination and antibacterial strategy utilized Services in many applications including self-cleaning environmental surfaces, water and air treatment.The present work reveals that antibacterial effects induced by photocatalysis can be maintained even after the cessation of UV irradiation
