Inhibition of biofilm of E. coli, P. aeruginosa, C. violaceum, K. pneumoniae, and S. aureus by AgNPs under scanning electron microscope (SEM). Biofilm formation by different bacterial agents were assessed by SEM. The biofilm treated by ½ × MIC of AgNPs showed reduction in the biofilm mass production compared with control untreated (scale bar 10 μm).
