Titania nanotube array was grown via anodization using different electrolyte chemistry to understand the influence of solution chemistry and pH on nanotube growth kinetics. One of the electrolytes was selected to evaluate the transformation in the surface morphology as a function of anodization time from 5 to 120 min. Contact angles were measured and surface energies were calculated on selected compositions for various duration of anodization time. It was noticed that contact angle decreased and surface energy increased with the onset of nanotube formation. Human osteoblast cell attachment and proliferation were studied using an osteo precursor cell line. Nanotube surface showed enhanced cell spreading, high cell proliferation, and abundant amount of extracellular matrix formation.
