The use of implants to repair or replace joints has increased dramatically and continues to increase today. Ensuring that the implant remains stable within the surrounding bone is one way to extend the life of the implant. Chitosan, a derivative of chitin from shrimp shells, has been shown to attract bone cells and encourage bone cell attachment and growth, thereby stabilizing the implant. Modification of the titanium surface is required to bond chitosan, due to the passive nature of titanium. The use of toluene to deposit aminopropyltriethoxysilane (APTES) on the titanium surface as a linker to chitosan has significantly increased the adhesion strength of the coating, although toluene has significant health effects, including being carcinogenic and mutagenic. The research presented will examine the surface chemistry required to bond chitosan to titanium, as well as the adhesion strength of the bonded chitosan coating using APTES and one of three biocompatible solvents.
