Abstract
A single-step electrophoretic deposition (EPD) process from aqueous suspension was used to assess novel composite coating of hydroxyapatite (HAP) with natural polymer chitosan (CS) and antibiotic, gentamicin (Gent). EPD was carried out at constant voltage on pure titanium plates. In order to investigate the gentamicin influence on physico-chemical and biological properties of composite coatings, detailed characterization was performed. For that purpose X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and fieldemission scanning electron microscopy (FE-SEM) were used. Obtained results confirmed the formation of a new composite HAP/CS/Gent coating. Potential application was examined through biological assays. The gentamicin addition strongly improved the antibacterial activity of HAP/CS/Gent coating that was confirmed by agar diffusion method and test in suspension. Obtained results indicated more pronounced antibacterial effect against Staphylococcus a...ureus compared to Escherichia coli. MTT and DET tests indicated low cytotoxicity against MRC-5 and L929 tested cell lines, indicating good biocompatibility of obtained composites. MRC-5 human cell line responded better in cytotoxicity testing, pointing to encouraging results for potential application. The ability of biomineralization promotion was noticed through the ALP assay. Therefore, HAP/CS/Gent coating can be considered as perspective material for bone tissue engineering as hard tissue implant.
