Enhancement of biocompatibility of anodic nanotube structures on biomedical Ti-6Al-4V alloy via ultrathin TiO₂ coatings.

ABSTRACT: This work aims to describe the effect of the surface modification of TiO₂ nanotube (TNT) layers on Ti-6Al-4V (TiAlV) alloy by ultrathin TiO₂ coatings prepared via Atomic Layer Deposition (ALD) on the growth of MG-63 osteoblastic cells. The TNT layers with two distinctly different inner diameters, namely ∼15 nm and ∼50 nm, were prepared via anodic oxidation of the TiAlV alloy. Flat, i.e., non-anodized, TiAlV alloy foils were used as reference substrates. Additionally, a part of the TNT layers and alloy foils was coated with ultrathin coatings of TiO₂ by ALD. The number of TiO₂ ALD cycles used was 1 and 5 leading to a nominal TiO₂ thickness of ∼0.055 and ∼0.3 nm, respectively. The ultrathin TiO₂ coating by ALD enabled to optim
