Effect of nano - topographical features of Ti/TiO2 electrode surface on cell response and electrochemical stability in artificial saliva

The paper is a new approach which aims to evaluate the relation between surface aspects (wettability and roughness) of materials based on titanium with native passive TiO2 as untreated samples and TiO2 nanotubes as treated discs respectively, their electrochemical stability in artificial saliva, and fibroblast cell behaviour.Ti/TiO2 modified electrodes as nanotubes with 120nm as diameter were obtained using an electrochemical method as anodizing and surface analysis as SEM, AFM and contact angle measurements were performed to obtain topographical features and wettability.The TiO2 nanotube structured oxide films electrochemical growth increase the stability of titanium surfaces. The electrochemical behavior of Ti/ TiO2...
