Fig. 9From: Synthesis of graphene oxide-quaternary ammonium nanocomposite with synergistic antibacterial activity to promote infected wound healinga Cell viability measured using CCK-8 assay after cells being incubated with different concentrations of GO and GO-QAS suspensions for 24 h. b FACS results showing cell apoptosis and necrosis distribution after GO and GO-QAS incubation based on the Annexin V–FITC and PI assay. Statistical analysis of c necrosis cells ratio and d apoptosis cells ratio. e Hemocompatibility of GO-QAS at different concentrations. (ns represents p > 0.05; ****p < 0.0001). (CCK-8: cell counting kit-8; GO: graphene oxide; GO-QAS: graphene oxide-quaternary ammonium salt; FACS: fluorescence-activated cell sorting; PI: propidium iodide)Back to article page
