| description | Bifunctionalized mesoporous silicasupported gold nanoparticles as oxidase and peroxidase mimics for antibacterial applications are demonstrated. For the first time, these mesoporous silica‐supported gold nanoparticles are applied as oxidase and peroxidase mimics. Taking advantage of their prominent enzyme activities, the MSN‐AuNPs show excellent antibacterial properties against both Gram‐negative and Gram‐positive bacteria. Furthermore, MSN‐AuNPs also exhibit outstanding performance in biofilm elimination . |
