E-scaffold enhances tobramycin susceptibility in P. aeruginosa PAO1 biofilms. Bars represent means of logarithms of colony-forming units of viable biofilm cells. Error bars represent the standard error of the means from three biological replicates. The symbols *, **, ***, and **** represent significant differences in tobramycin susceptibility between e-scaffold treated biofilms + tobramycin and untreated biofilms + tobramycin (n = 3, *, P = 0.002; **, ***, **** P ≤ 0.001; paired t-test)
