Ultrathin ALD Coatings of Zr and V Oxides on Anodic TiO₂ Nanotube Layers: Comparison of the Osteoblast Cell Growth.

ABSTRACT: The current study investigates and compares the biological effects of ultrathin conformal coatings of zirconium dioxide (ZrO₂) and vanadium pentoxide (V₂O₅) on osteoblastic MG-63 cells grown on TiO₂ nanotube layers (TNTs). Coatings were achieved by the atomic layer deposition (ALD) technique. TNTs with average tube diameters of 15, 30, and 100 nm were fabricated on Ti substrates (via electrochemical anodization) and were used as primary substrates for the study. The MG-63 cell growth and proliferation after 48 h of incubation on hybrid TNTs/ZrO₂ and TNTs/V₂O₅ surfaces was evaluated in comparison to the uncoated TNTs of each diameter. The density of viable MG-63 cells was assessed for all the TNT surfaces, along wi
