This study demonstrated an anodic deposition of hydroxyapatite (HA) with Ag nanoparticles (NPs) on titanium implants to enhance anti-bacterial ability and bioactivity concurrently. The anodic deposition processes were carried out in electrolytes containing HA NPs with 0-1 g/l Ag NPs. Microstructural observation exhibited that some micro-cracks and destructions were locally found due to the high electrical stress in the case of 1 g/l Ag NPs. However, the patterns of X-ray diffraction showed no changes of compositions of all coatings. For this reason, all coatings revealed nearly similar cytocompatibilities, according to the cell tests using MC3T3-E1 osteoblast. Meanwhile, anti-bacterial test using E.coli and staphylococcus showed that both bacteria were completely killed on the coatings produced in the electrolyte with Ag NPs 0.5 and 1 g/l. Consequently, the HA coating produced in the electrolyte with 0.5 g/l Ag NPs exhibited the superior anti-bacterial ability and bioactivity.
