In vitro cytotoxicity of PEG-GO-PEI-FA/siRNA in ovarian cancer SKOV3 cells via CCK-8 assay. a SKOV3 cells were treated with PEG-GO-PEI and PEG-GO-PEI-FA at different concentrations (10–500 μg/mL) at 12 and 24 h to get the optimal dose of nanocarrier. b The cytotoxicity of PEG-GO-PEI-FA/siRNA, PEG-GO-PEI/siRNA, and Lipo2000/siRNA were measured in different time points (4–48 h) at 100 μg/mL. Error bars represent ± SD; *p < 0.05 (Student’s t test)
