Investigation of antibacterial calcium phosphate / chitosan / zinc coating synthesized by sol-gel method
Özet
Although calcium phosphate coatings, which are widely used in orthopedic or dental implant applications, have excellent bioactivity and osteoconductivity, they carry a risk of infection. In this study, calcium phosphate / chitosan / zinc containing biocomposite coating, which provides both bioactive and antibacterial properties on the surface of Titanium, was obtained by sol-gel method. The characterization studies of the coating were carried out by X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersion Spectroscopy (EDS) and Fourier Transform Infrared Spectroscopy (FTIR) analyzes. The addition of biocompatible chitosan and zinc to the calcium phosphate-containing coating has provided antibacterial properties. According to the results, this coating, which was developed without using antibiotics to prevent postoperative surgical infections, is promising. © 2021, TUBITAK. All rights reserved.
