Fabricated Antibacterial and Bioactive Titania Nanotube Arrays Coating on the Surface of Titanium

Abstract

By photic-assisted deposition, Ag nanoparticles were assembled on bioactive TiO2 nanotube arrays, which were fabricated by anodic oxidation in 0.5 wt% NH4F solution containing 0.5 wt% Na2HPO4. The samples were characterized by scanning electron mincroscope (SEM), X-ray diffraction (XRD). Germiculture experimentation was employed to testing samples’ antibacterial capability. An obvious antibacterial ring appeared around the Ag modified samples, indicating that Ag modified titania nanotube arrays has good antibacterial capability.
