We report the first antimicrobial study of transparent and robust Cu-doped ZnO coatings that displayed potent antimicrobial activity that resulted in bacterial () reduction below detection limits within 6 h of illumination via a white light source that is found in hospital environments. The same bacterial reduction rate was observed even under darkness for 4.0 atom % Cu-doped ZnO films thus providing an efficient 24 h disinfection. All films were produced via a novel, inexpensive, and easily scalable route and were also thoroughly analyzed for their material properties.
我们报告了对透明且坚固的铜掺杂氧化锌涂层的首次抗菌研究，该涂层展现出强大的抗菌活性，通过医院环境中常见的白光源照射，在6小时内可使细菌（）减少至检测限以下。对于4.0原子%的铜掺杂氧化锌薄膜，即使在黑暗条件下也观察到相同的细菌减少率，从而实现了高效的24小时消毒。所有薄膜均通过一种新颖、廉价且易于扩展的方法制备，并对其材料特性进行了全面分析。
