Figure 6

Images representing MMP loss in CHANG and HepG2 cells after rGO–Ag nanocomposite exposure at concentrations of 25 and 50 µg/mL for 24 h.

Notes: (A) Control cells. (B) rGO–Ag nanocomposite exposure, 25 µg/mL for 24 h and (C) 50 µg/mL for 24 h. (D) Change in MMP (%) in CHANG and HepG2 cells after rGO–Ag nanocomposite exposure for 24 h. Each value represents the mean±SE of three experiments. *p<0.05 and **p<0.01 vs control.

Abbreviations: rGO–Ag, silver-doped reduced graphene oxide; MMP, mitochondrial membrane potential; SE, standard error.
