TA biocomposite coating, containing chitosan silver and hydroxyapatite, was developed on anodized tita-nium substrate by. Electrochemical deposition. Coatings were characterized by field-emission SCANNINGELECTRON microscopy X-ray diffraction,,, Fourier transform infrared spectroscopy X-ray photoelectronspectroscopy, and polarisation studies. Results showed that the. Prepared coatings had compact and densemorphology with a thickness of 6.2 edge 0.7 m and that silver was evenly, distributed. Testing the preparedcoatings with Gram-positive and Gram-negative bacterial strains exhibited antibacterial activity becauseof. The synergistic effect of silver and chitosan. The prepared coatings were also found to be nontoxic toMC3T3-E1 cells. These. Results suggested that chitosan / silver-hydroxyapatite biocomposite coatings canprevent the bacterial infection of implants.
