Electrical polarization processes were investigated on 45S5 type bioactive glass (BG) with the composition of 24.5 Na₂O, 24.5 CaO, 45.0 SiO₂ and 6.0 P₂O₅ (wt%). From the results of the thermally stimulated depolarization current measurements, two polarization processes were confirmed, which are considered due to the two migration processes of sodium ions during polarization. The processes depended on a magnitude of a dc field applied during polarization. Besides, the polarized surface reactions with blood interaction were studied. The surface charges on the BG were found to cause a change in the adhesion of some plasma proteins to the surface.
