GO and UA-rGO induce caspase-3 activity in human ovarian cancer cells. Ovarian cancer cells were treated with GO or UA-rGO with or without caspase-3 inhibitor Ac-DEVD-CHO for 24 h. The concentration of p-nitroanilide released from the substrate was calculated from the absorbance at 405 nm. The results are expressed as the mean ± standard deviation of three separate experiments. The treated groups showed statistically significant differences from the control group by the Student’s t-test (p < 0.05).
