Inhibition of P. aeruginosa biofilm by PG-AuNPs and PG-ZnONPs. (A) Antibiofilm effect of PG-AuNPs and PG-ZnONPs and (B) growth properties in the presence of PG-AuNPs and PG-ZnONPs. The biofilm assays were carried out via staining with crystal violet and quantified by measuring the OD at 570 nm. The cell culture (OD 0.05) was treated with different concentrations of NPs and incubated at 37 °C for 24 h. Statistical analysis was carried out using one-way ANOVA, followed by Dunnett’s multiple comparisons test. *** and * denote significance at p < 0.0001 and p < 0.05, respectively, in one-way ANOVA.
