Abstract
Ultraviolet (UV) light was irradiated in air for 1 h on titania (anatase) films sol-gel derived on Ti, stainless steel, alumina, and glass slide substrates, coded as C5Ti, C5SUS, C5Al2O3 and C5GS, respectively. They were then soaked in a simulated body fluid (SBF, Kokubo solution) and their apatite-forming ability (bioactivity) was evaluated. UV light irradiated C5SUS deposited bone-like apatite within 7 days whereas C5SUS did not within 7 days. Moreover, the apatite was deposited faster on UV light irradiated C5Ti than on C5Ti without UV light irradiation, whereas UV light irradiated C5GS, C5A12O3 and C5GS did not apatite within 7 days. Therefore, the ultraviolet light irradiation was confirmed to enhance in vitro apatite-forming ability of the sol-gel derived titania films on various substrates, but the effect depended on substrates.
