Caspases spectrophotometric analysis of HeLa cells after treating with SG-stabilized AuNPs for 24, 48 and 72 h. Values are expressed as mean ± SD of three different experiments. The data has been analyzed using post hoc comparison test-one way ANOVA, means compare with Tukey’s-b test. (*): significant (p < 0.05) increasing of apoptotic cells in SG-stabilized AuNPs treated groups in comparing to that of untreated controls.
