| 英文摘要 | To reduce the risk of implant-associated infections, we previously designed and developed a series of medical copper (Cu)-bearing titanium alloys that release Cu ions and hence play an antibacterial role. However, both excessive and deficient Cu levels adversely affect human health; therefore, the aim of the present study was to comprehensively evaluate the short-and long-term biosafety of Cu-bearing titanium alloys (Ti6Al4V-Cu and Ti-Cu) both in vitro and in vivo . Moreover, the predominant kinetic mechanism of Cu ions release and its effect on biosafety were also investigated. The results indicate that the biocompatibility of the Cu-bearing titanium alloys meets the requirements of ISO standards and the Cu ion release kinetics display a good correlation over the entire time period in the normal zero-order model with an almost constant release rate. The release rate maintained at a parts per billion level safe for humans; consequently, we can conclude that our Cu-bearing titanium alloys have satisfactory biocompatibility.
