A silicon-containing apatite layer was prepared on a metallic titanium substrate coated with a silica layer. The silica layer on a titanium substrate was derived from water glass through heat-treatment at 300 °C for 2 hr and subsequent acid-treatment using 0.1 N-HCl at 50 °C for 2 hr. The silica layer was homogeneously coated with nano-sized vaterite powders (~ 0.5 μm in diameter). The vaterite coating was achieved by utilizing the interaction of surface potentials between the positively charged vaterite and the negatively charged silica layer. After soaking the sample in simulated body fluid at 37 °C for 3 days, hydroxyapatite (HA) formed on the surface of the silica-coated titanium. The HA layer was found to include a trace amount of releasable silicon, which may enhance the osteoblast proliferation.

Weak Acidic Condition

Acetic acid contributes to the strong ionic interaction between Si ions and chitosan by providing a weak acidic condition, and its steric hindrance effect leads to the formation of nanosized silica particles and their homogeneous distribution.
