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.
