Nanotubular structured titanium (Ti) substrates have been coated with nanoparticulate hydroxyapatite (nano-HA). The nano-HA surface is highly adherent to the nanotubular Ti surface and is free of microparticles. The nano-HA coated nanotubular Ti surface promotes osteoblast cell adhesion and is particularly suitable for orthopedic and dental implants where deposition of osteoblasts and other proteins is important in bone formation.
