Transparent antimicrobial coatings can maintain the aesthetic appeal of surfaces and the functionality of a touch-screen while adding the benefit of reducing disease transmission. We fabricated an antimicrobial coating of silver oxide particles in a silicate matrix on glass. The matrix was grown by a modified Stöber sol-gel process with vapor-phase water and ammonia. A coating on glass with 2.4 mg of AgO per mm caused a reduction of 99.3% of SARS-CoV-2 and >99.5% of , , and methicillin-resistant compared to the uncoated glass after 1 h. We envisage that screen protectors with transparent antimicrobial coatings will find particular application to communal touch-screens, such as in supermarkets and other check-out or check-in facilities where a number of individuals utilize the same touch-screen in a short interval.
透明抗菌涂层可以在保持表面美观和触摸屏功能的同时，减少疾病传播。我们在玻璃上制备了一种氧化银颗粒在硅酸盐基质中的抗菌涂层。该基质是通过改进的 Stöber 溶胶-凝胶工艺，在气相中用水和氨生长而成的。与未涂层的玻璃相比，在玻璃上涂覆一层 2.4mg/mm 的 AgO，在 1 小时后，可使 SARS-CoV-2 减少 99.3%， 、 和耐甲氧西林金黄色葡萄球菌减少 >99.5%。我们设想，具有透明抗菌涂层的屏幕保护膜将特别适用于公共触摸屏，例如在超市和其他结账或登记设施中，许多人在短时间内使用同一个触摸屏。
