Cytotoxicity of rGO–Ag nanocomposite in CHANG and HepG2 cells for 24 h, as determined by (A) MTT and (B) LDH tests. Each value represents the mean±SE of three experiments. n=3, *p<0.05 and **p<0.01 vs control. A significant positive correlation between the LDH leakage and MTT cell viability in CHANG cells (C) and HepG2 cells (D) after rGO–Ag nanocomposite exposure.
Abbreviations: rGO–Ag, silver-doped reduced graphene oxide; LDH, lactate dehydrogenase; SE, standard error.
