From: Exposure to polystyrene nanoparticles leads to changes in the zeta potential of bacterial cells
The zeta potential-pH profiles in 0.3 mM NaCl obtained for S. aureus strain ATCC 6538 (a), and K. pneumoniae strain ATCC 4352 (b). Bacterial cells were untreated (filled orange rhombus) or treated with 0.4 (filled grey rhombus), 2 (filled green rhombus), 20 (filled dark blue rhombus), and 100 (filled brown rhombus) µg/ml of polystyrene nanoparticles. Statistical analysis is presented in Tables S1 and S2 of the Supplementary Material.
