Antibacterial properties of Ag/TiO₂/PDA nanofilm on anodized 316L stainless steel substrate under illumination by a normal flashlight.

ABSTRACT: The demand of medical materials for rapid and efficient elimination of bacteria has seen a dramatic surge over the past few years. In this study, antibacterial nanofilms with reactive oxygen species were generated by photocatalysis. To prepare these nanofilms, Ag and amorphous TiO₂ nanoparticles decorated on polydopamine (PDA) were coated on three-dimensional (3D) nanopore arrays, which was fabricated on a substrate of anodized stainless steel. All the antibacterial tests were conducted with a household flashlight, which may be considered as a practical approach for antibacterial materials. The photoelectrochemical property of the 3D Ag/TiO₂/PDA nanofilm on 316L stainless steel (Ag/TiO₂/PDA SS) was about 15 times higher than that of the annealed Ag/TiO
