From the dinner table to the office, many surfaces contain bacteria and the threat to human health. In this work, cost-effective antimicrobial foams were developed by the adsorption of lysozyme protected gold nanoclusters (AuNCs) in sponges. Antibacterial activities of the prepared antibacterial AuNCs were evaluated using typical Gram-negative bacteria (Escherichia coli) and Gram-positive bacteria (Staphylococcus aureus). The antibacterial foams were further fabricated by the absorption of the positively charged AuNCs in the negatively charged sponges. The inhibitions of bacteria on random surfaces, such as mobile phones, tables, doorknobs, and cabinet handles, were exhibited by cleaning them with the antibacterial foams.

使用金纳米团簇制备抗菌海绵清洁剂。

从餐桌到办公室，许多表面都含有细菌，对人类健康构成威胁。在这项工作中，通过在海绵中吸附溶菌酶保护的金纳米簇 (AuNC) 开发了具有成本效益的抗菌泡沫。使用典型的革兰氏阴性菌（大肠杆菌）和革兰氏阳性菌（金黄色葡萄球菌）评估制备的抗菌 AuNCs 的抗菌活性。通过在带负电的海绵中吸收带正电的 AuNC 进一步制造抗菌泡沫。通过用抗菌泡沫清洁它们来展示对随机表面（例如手机、桌子、门把手和橱柜把手）的细菌抑制作用。
