中文摘要：

氧化镁基纳米材料作为一类新型的抗菌材料,具有持久和广谱的抗菌活性,而且安全无毒、热稳定性好、无需光照诱导,因此成为抗菌消毒领域的研究热点,但是其抗菌机理一直存有争议.文章介绍了几种近年来被广泛接受的抗菌机理,以及利用先进的研究方法在氧化镁基纳米材料的抗菌机理研究方面所取得的最新进展,指出了其对新型无机纳米抗菌材料合成的指导意义.

英文摘要：

Magnesium oxide nano-materials, a group of novel antibacterial materials with low toxicity, high thermal stability, and permanent and broad-spectrum antibacterial activity even under dark condition, have been a research focus in the field of disinfectants. But there are still disputes in terms of their antibacterial mechanism. In this article, several commonly accepted antibacterial mechanisms of magnesium oxide nano-materials, as well as some most recent research progress in this aspect achieved by using some advanced methodology, are introduced. The significance of these research results in guiding the synthesis of novel inorganic antibacterial nano-materials is also disgussed.
