Films with well-controlled porous structures provide many exciting application opportunities in chemistry and biology1,2. Here we report the synthesis of a highly uniform, hierarchically ordered nanoporous poly (methyl methacrylate) PMMA film structures, and its application as antibacterial supports. SiO2 nanoparticle and sodium dodecyl lauryl sulphate (SDS) breath figure templating approach was applied for fabrication of ordered porous polymer films and functional hybrid films with distinct pore sizes3. The incorporation of desired non-polymeric components, such as COOH-functionalized silver sulphide quantum dot (Ag2S) nanoparticles with distinct tunable light emission from 500 to 1000 nm and a QD diameter size between 1.5 and 9 nm, shows visible-light enhanced inhibition of E. coli growth4
