title: Effect of Mg ion bioactivity on the TiO2 nano-network surface.
abstract: Magnesium (Mg) ion is well known for improving the Ca-P nucleation and growth. TiO2 nano-network (NT) surface was prepared by alkali-treatment. To introduce the Mg ion to TiO2 NT surface, acrylic acid plasma polymerization was used. Bioactivity of the Mg ions coated samples was evaluated by immersed in simulated body fluid (SBF). Surface morphology and chemical composition of all samples were characterized by SEM, XRD and XPS. Mg ion promotes hydroxyapatite (HA) nucleation and growth on TiO2 NT in SBF and improves crystallinity of HA deposited layer.
