Anti-biofilm activities of AgNP–CFCS and AgNP-culture against Psa strain ML2-12 and T6-1 determined by crystal violet staining of biofilms and propidium iodide staining of dead cells. a Absorbance of crystal violet at 590 nm (OD590) indicates Psa cells in biofilms. Data are presented as mean values with standard deviation (vertical bars); the different letters on the vertical bars indicate significant difference between treatments according to one-way analysis of variance at the significance level p < 0.05. b Flow cytometry analyses show dot plots of fluorescence signals from dead Psa cells stained by propidium iodide against sideward scatter (SSC), indicate percentage of dead cells in total cells of the biofilms formed under AgNPs
