In Vitro Apatite-Forming Ability of Titania Films Depends on Their Substrates

Abstract:

Titania films were coated by means of sol-gel method on various substrates such as titanium, titanium alloy, silicon wafer, stainless-steel, alumina, and glass slide where they coded as C5Ti, C5Ti6Al4V, C5Si, C5SUS, C5Al2O3 and C5GS, respectively. Their in vitro apatite-forming ability was examined with the Kokubo’s simulated body fluid (SBF; pH 7.4, 36.5°C). C5Ti, C5Ti6Al4V and C5Si deposited apatite particles on their surface within 7 days, whereas, C5SUS, C5Al2O3 and C5GS did not. These results implied that the in vitro apatite-forming ability of the titania films indirectly depended on the chemical or physical properties of the substrates.
