Abstract
The battle against postoperative infection in orthopedic surgery calls for the development of surfaces with antibacterial activity on the implant side of the bacterial biofilm. Incorporation of nanosilver into titanium nanotube surfaces offers a potential solution. This study presents a novel single-step anodization approach to incorporating nanosilver particles within and among anodized titanium nanotubes on implant surfaces using a new hybrid electrolyte. The amount of nanosilver deposited on the titanium nanotubes was analyzed by varying the silver concentration in the hybrid electrolyte. Successful fabrication of titanium nanotubes by anodization of foils, rods and thermal plasma-sprayed surfaces of Ti6Al4V, and simultaneous nanosilver deposition was quantified by field emission scanning electron microscopy, transmission electron microscopy and X-ray energy-dispersive spectroscopy. Upon post-anodization heat treatment, the amorphous to anatase conversion of these structures was confirmed using X-ray diffraction analysis. This study presents a simple single-step fabrication of antibacterial titanium nanotube surfaces allowing controlled nanosilver deposition needed to avoid unintended cytotoxicity.
