Fig. 8From: Synthesis of graphene oxide-quaternary ammonium nanocomposite with synergistic antibacterial activity to promote infected wound healinga The absorbance of efflux of cytoplasmic materials (DNA and RNA) at 260 nm after bacteria being incubated with GO, QAS, and GO-QAS at 200 μg/mL, respectively. b ROS generation after the bacteria suspensions were incubated with GO, QAS, and GO-QAS dispersions at 200 μg/mL concentration. (**p < 0.01, ***p < 0.001, ****p < 0.0001). (GO: graphene oxide; QAS: quaternary ammonium salt; GO-QAS: graphene oxide-quaternary ammonium salt; ROS: reactive oxygen species)Back to article page
