Abstract
OBJECTIVE: To discuss the biosafety and biocompatibility of biomaterials. METHODS: A computer-based online search of CNKI, CBM and VIP as well as manual search were performed to collect articles about random cell control experiments and animal experiments of biological material biocompatibility published between 1990 and 2008. A total of 28 Chinese literatures were collected, and 7 were included mainly involving the cytotoxicity test methods and blood compatibility of the experimental medium, experimental grouping, experimental materials, methods of observation, experimental results, and experimental conclusion. In addition, biocompatibility of the biological material was analyzed to summarize the biocompatibility of the biological safety. RESULTS: Based on experiments of biosafety and biocompatibility of biomaterials, the cytotoxicity test and blood compatibility of various biomaterials, such as collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, are essential for the biological safety. The experimental results have shown that the biomaterials have good biocompatibility. CONCLUSION: A variety of biological materials present good biocompatibility, including collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, based on the evaluation criteria.关键词
