| Abstract Scope |
The recent works of biomedical zinc and its alloys will be reported in this talk. Firstly the in vivo degradation of pure zinc stent within the blood vessel microenvironment will be presented; secondly several kinds of Zn-based biocomposites aiming for orthopaedic application usage were developed, and their in vivo degradation behavior within bone microenvironment will be reported; thirdly we will show you our works on the development of binary Zn alloys, with over 10 kinds of alloying elements were added into Zn to enhance its mechanical properties and bioactivities; finally we will demonstrate how to use surface modification techniques to adjust the degradation rate and enhance the biocompatibility of pure Zn. All these preliminary in vitro and in vivo studies showed acceptable biodegradability and reasonable biocompatibility in the bone and blood micro-environments for the experimental Zn-based biodegradable metals, and for some alloy systems superior mechanical performance than biomedical Mg alloys. |
