Short Review: Effect of UV Light on Precipitation of Hydroxyapatite on TiO2 in Simulated Body Fluid

Abstract

A number of previous studies on titanium dioxide (TiO2) proven the presence of anatase has enhance hydroxyapatite (HAP) precipitation on TiO2surface which beneficial for biomedical usage especially in dental and orthopedics. The anatase phase of TiO2is an ideal photocatalyst agent. It helps to enhance the chemical reaction after irradiating with ultra violet (UV) light. The effect of UV light irradiation to the precipitation of HAP on TiO2surface while soaking in simulated body fluid (SBF) increased the formation of HAP. UV light also can be applied as pre-treatment, where UV light was irradiating before SBF immersion.
