纳米 ZnO 是一种常见的光学材料，将其与其他材料复配可以制得抗菌性能良好的包装材料。根据 GB/T 21510-2008《纳米无机材料抗菌性能检测方法》，以大肠杆菌和金黄色葡萄球菌为测试菌种，以SiO2为对照试验，测试了纳米 ZnO 对大肠杆菌和金黄色葡萄球菌的抗菌性能；同时，采用抑菌圈法对其抗菌性能进行了定性研究。结果表明：纳米 ZnO 对大肠杆菌和金黄色葡萄球菌具有良好的抑菌性能，且初步测定了纳米 ZnO 对这两种菌的最小抑菌浓度，分别为0.3125%和0.625%；纳米 ZnO 对大肠杆菌和金黄色葡萄球菌高度敏感，纳米 ZnO 对二者的抑菌圈直径都大于15 mm。

Nanometer ZnO is a common optical material which can be processed into an antibacterial packaging material while compounding with other materials. According to GB/T 21510-2008 of Detection Method for Antibacterial Properties of Nanometer Inorganic Material, adopting SiO2 for controlled trials, the antibacterial properties of nanometer ZnO was tested against Escherichia coli and staphylococcus aureus strains. The qualitative research was conducted using bacteriostatic circle method. The result showed that nanometer ZnO performed well in antibacterial activity against the tested bacteria. The minimum inhibitory concentration of the nanometer ZnO was initially determined as 0.312 5% and 0.625% respectively for the tested bacteria. Nanometer ZnO was highly sensitive to these two kinds of tested bacteria with the antibacterial circle diameter greater than 15 mm in both cases.
