Fluorescence microscope images of a Escherichia coli and c Staphylococcus aureus in (a) control, (b) GO, (c) QAS, and (d) GO-QAS groups after being stained with SYTO 9 and PI (scale bars 20 μm). The cells were observed directly at ×100 magnification by laser confocal microscopy. Red stands for dead cells and green stands for total cells. Cell mortality ratio of b Escherichia coli and d Staphylococcus aureus after GO, QAS, and GO-QAS incubation. (*p < 0.05, **p < 0.01, ***p < 0.001). (GO: graphene oxide; QAS: quaternary ammonium salt; GO-QAS: graphene oxide-quaternary ammonium salt; PI: propidium iodide; S. aureus: Staphylococcus aureus; E. coli: Escherichia coli)
