【摘要】BACKGROUND: The zinc oxide has a good biocompatibility, security and long effectiveness, and can be used as a type of antibacterial material of active oxide category. OBJECTIVE: To summarize the antibacterial properties and mechanism of nano-zinc oxide (nano-ZnO). METHODS: A computer-based online search of related papers from December 1995 to February 2011 was performed in Elsevier (Science Direct) and Web of Science databases using the key words of " antibacterial properties of nano-ZnO" in English, and in CNKI and Wanfang databases using the key words of " antibacterial properti es of nano-ZnO" in Chinese. Totally 75 literatures were selected. RESULTS AND CONCLUSION: The nano-ZnO has a strong bactericidal property in many fields. It can replace other materials of active oxide category based on its good biocompatibility, security and long effectiveness. The antibacterial properties and mechanism of nano-ZnO were summarized in this study from the sides of modified antibacterial properties and the effects of morphology and structure of nano-ZnO on antibacterial properties. However, more studies are in need to solve how to improve the utilization and antibacterial properties, and to expand the
