Effect of different concentrations of (a) Ag-NPs and (b) Cu-NPs on mature biofilm of A. baumannii ATCC 19606, K. pneumoniae ATCC 33495, K. pneumoniae ATCC 51503, P. aeruginosa PAO1 standard strains and A. baumannii (A10, A11), K. pneumoniae (K7, K20) and P. aeruginosa (P2, P26) clinical isolates. The biofilm was stained with CV. Values represent the mean ± SD of three independent experiments (*, significant, P < 0.001)
