Fig. 7: Flow cytometry analysis of feed and permeate samples.

a Flow cytometry density plots and % count showing E. coli populations (live and dead cells) in the feed and permeate samples for Pristine-BC and BC-GO membranes with 0.0, 0.5, and 2.0 mg/mL GO concentrations. b Quantitative analysis for total count of E. coli populations in the feed. c % reduction of E.coli population after filtration with M 0.0, M 0.5 and M 2.0 membranes in terms of membrane compromised cell counts (MCCs), intact cell counts (ICCs), and total count in permeate, illustrating the effect of varying GO concentrations on E. coli rejection efficiency.
