Representative colonization of E. coli and S. epidermids on the PVC substrates before and after coating with PADA and Cu-DOTA, Azide/Cu-DOTA and AMP@Cu-DOTA. a) Colonization photographs of E. coli and S. epidermids. The antibacterial rate of different surfaces against E. coli (b) and S. epidermids (c) performed by Solid Medium method. The antibacterial rate of different surfaces against E. coli (d) and S. epidermids (e) performed by solution method. Data are presented as mean ± SD (n = 4) and analyzed by one-way ANOVA (***p < 0.001).
