Antibacterial Properties of Silver‐Doped Titania

Abstract

Silver-doped titania nanoparticles (see image) in specific concentrations show a higher efficacy than pure silver nanoparticles towards the inhibition and annihilation of E. coli bacteria. The doped titania particles are synthesized via a sol–gel method. Antibacterial studies of the silver-doped titania particles in both a liquid-nutrient growth medium and on agar plates are shown; this approach may offer a simple low-cost method for fabricating antibacterial surfaces.
