The bioactivity mechanism of magnetron sputtered bioglass thin films

► RF-sputtering: an efficient solution for synthesizing bioactive glass thin films. ► Electrostatic interactions between charged surface and ions from stagnant solution. ► Heterogeneous-type nucleation of apatite from the SBF solution on the glass surface. ► Peculiarities of hydroxyapatite nucleation process and biomineralisation kinetics.
