Photosensitized TiO2 nanomaterials for visible-light antimicrobial photodynamic inactivation
Photodynamic inactivation (PDI) can exploit molecular photosensitizer photochemistry and semiconductor-mediated redox processes, while biological activity depends on how these mechanisms operate at the material–microbe interface. Colloidal nanocrystalline TiO 2 (qTiO 2 ) was surface-sensitized with 5,10,15,20...
