Abstract

Titania loaded with noble metal nanoparticles exhibits enhanced photocatalytic killing of bacteria under light illumination due to the localized surface plasmon resonance (LSPR) property. It has been shown recently that loading with Au or Ag can also endow TiO₂ with the antibacterial ability in the absence of light. In this work, the antibacterial mechanism of Au-loaded TiO₂ nanotubes (Au
