Sunlight‐Sensitive Plasmonic Nanostructured Composites as Photocatalytic Coating with Antibacterial Properties

Infections caused by microorganisms are a global public health problem that continually demands new antimicrobial strategies. The generation of reactive oxygen species (ROS) photocatalytic materials is an attractive approach to combat microbes. Along these lines, titanium dioxide (TiO2) constitutes outstanding light-driven ROS generator. However, the wide bandgap this semiconductor limits its use ultraviolet range spectral region. Herein, nanostructured composed TiO2 nanoparticles and plasmonic gold nanorods (AuNRs) presented for photoinactivation bacteria means sunlight irradiation, aiming extend action nanocomposite visible near-infrared ranges. It shown that, upon simulated different composites as coating films show photodegradation rhodamine B, production, inactivation protein function in bacterial biofilms, strong activity. This involving AuNRs/TiO2 may pave way fabrication light-responsive surfaces with
