Abstract

Silver nanoparticle-incorporated TiO2 nanotubes (Ag/TiO2-NTs) were successfully synthesized by anodization and immersion in a silver nitrate solution followed by ultraviolet light radiation. The obtained Ag/TiO2-NT samples were characterized by SEM, TEM and EDS, and the results show that the silver nanoparticles adhere strongly to the inner walls of the nanotubes along the entire length. The antibacterial ability to Escherichia coli and Staphylococcus aureus was also evaluated, and indicated that the incorporation of Ag was effective to restrain the growth of the testing bacteria.
