a Viable plate counts of bacteria in 7- and 15-day biofilm samples. b Live-dead bacterial cell counts estimated by flow-cytometry analysis of 7- and 15-day biofilm samples. c Quantification of malondialdehyde (MDA) in 7- and 15-day biofilm samples exposed to differentially charged NPs at 100 mg/L concentration, * denotes significance at p < 0.05. d Catalase (CAT) activity in 7- and 15-day biofilm samples, exposed to same set of NPs; *** denotes significance at p < 0.001, compared against the control. The data represents mean and standard error for triplicate experiments
