GO-100 and GO-20 graphene sheets inhibit proliferation of TM3 and TM4 cells. (A) The viability of TM3 cells was determined after 24 h exposure to different concentrations of GO-100 (20–100 µg/mL) and GO-20 (20–100 µg/mL), and (B) the viability TM4 cells was determined after 24 h exposure to different concentrations of GO-100 (20–100 µg/mL) and GO-20 (20–100 µg/mL) using the BrdU assay. The results are expressed as the mean ± standard deviation of three independent experiments. At least three independent experiments were performed for each sample. The treated groups showed statistically significant differences from the control group by Student’s t-test (* p < 0.05).
