Innovative Anodic Treatment to Obtain Stable Metallic Silver Micropatches on TiO₂ Nanotubes: Structural, Electrochemical, and Photochemical Properties.

ABSTRACT: Electrochemical modification of the Ti surface to obtain TiO₂ nanotubes (NT-Ti) has been proposed to enhance osseointegration in medical applications. However, susceptibility to microbial adhesion, linked to biomaterial-associated infections, and the high TiO₂ band gap energy, which allows light absorption almost exclusively in the ultraviolet (UV) region, limit its applications. Modifying the TiO₂ semiconductor with metals such as Ag has been suggested both for antimicrobial purposes and for absorbing light in the visible region. The formation of NT-Ti with Ag micropatches (Ag-NT-Ti) is pursued with the objective of enhancing the stability of the deposits and preventing cytotoxic levels of Ag cellular uptake. The innovative process proposed here involves i
