Background and Aims: In this study graphene oxide based coatings are applied on the titanium substrates in order to improve their biocompatibility and antibacterial properties of titanium substrate.
Materials and Methods: Chitosan, graphene oxide and their composites separately are coated on the substrates and their hydrophilicity and roughness are measured using contact angle measurement and atomic force microscopy. The coated substrates are then exposed to MG63 osteoblasts and Staphylococcus aureus in order to evaluate the interactions.
Results:  The results show that titanium samples that are coated with chitosan and composites have better surface hydrophilicity and higher roughness compared to other samples and uncoated titanium. Cell adhesion is also improved on the coated substrates. Regarding the antibacterial property the composite coating show the best results.
Conclusions: It is concluded that the titanium substrate which is coated with nanocomposite of graphene oxide and chitosan has higher hydrophilicity and roughness that resulted to enhance biocompatibility and antibacterial property. This may lead to a higher success rate in the application of these substrates in maxillofacial implant surgeries.
Keywords: Titanium, Graphene Oxide, Chitosan, Biocompatibility, Antibacterial
