Abstract
Surface modification with silver ion is an effective way to reduce infections. In the present work, the effect of silver ion-exchanged sodium titanate on the titanium has characterized by thin film X-ray diffraction analysis (TF-XRD) and high resolution scanning electron microscopy (HR-SEM). Antibacterial activity of silver ion-exchanged sodium titanate on titanium was assessed by the plate-counting method using against Staphylococcus aureus. The results show that silver ion-exchanged samples improve the antibacterial activity depends on NaOH concentration in electrolyte while the titanium oxide layer shows a significant decline. It is also found that the apatite-forming ability of silver ion-exchanged samples was showed after 7 days by immersion in SBF. In conclusion, silver ion-exchange method to the sodium-titanate is favorable to increase the antibacterial activity of titanium surfaces as well as apatite-forming ability
