Preparation and Antibacterial activity of Ag-Titania Nanotubes on Titanium surfaces

摘要

Highly dispersed Ag particles were well deposited on the surface of TNTs by means of photo-reduction. The size of Ag particles on the surface of titanium could be controlld by adjusting the concentration of AgNO_3 solution and the irradiated time of UV-light. Ag nanoparticles incorporated into TNTs remarkably enhanced the antibacterial activity of titanium surfaces.
