Figure 8From: Enhanced green fluorescent protein-mediated synthesis of biocompatible graphene Effects of GO and EGFP-rGO on cell viability of human embryonic kidney 293 cells. Cell viability of human kidney cells was determined using WST-8 assay after 24 hours exposure to different concentrations of GO or EGFP-rGO. The results represent the means of three separate experiments, and error bars represent the standard error of the mean. GO- and EGFP-rGO-treated groups showed statistically significant differences from the control group by the Student's t-test (P<0.05).Back to article page
