Ultrathin TiO₂ Coatings via Atomic Layer Deposition Strongly Improve Cellular Interactions on Planar and Nanotubular Biomedical Ti Substrates.

ABSTRACT: This work aims to investigate the chemical and/or structural modification of Ti and Ti-6Al-4V (TiAlV) alloy surfaces to possess even more favorable properties toward cell growth. These modifications were achieved by (i) growing TiO₂ nanotube layers on these substrates by anodization, (ii) surface coating by ultrathin TiO₂ atomic layer deposition (ALD), or (iii) by the combination of both. In particular, an ultrathin TiO₂ coating, achieved by 1 cycle of TiO₂ ALD, was intended to shade the impurities of F- and V-based species in tested materials while preserving the original structure and morphology. The cell growth on TiO₂-coated and uncoated TiO₂ nanotube layers, Ti foils, and TiAlV alloy foils were compared after incubation
