Effect of GO and S-rGO on cell viability of PMEF cells. Cell viability of PMEF cells was determined using WST-8 assay after a 24-h exposure to different concentrations of GO or S-rGO. The results represent the means of three separate experiments, and error bars represent the standard error of the mean. GO-treated groups showed statistically significant differences from the control group by Student’s t test (p < 0.05).
