Values are expressed as mean ± SD of three different experiments. The data has been analyzed using post hoc comparison test-one way ANOVA, means compared by Tukey’s- test. (): significant () increased early apoptotic cells in S-GNPs treated groups compared to untreated controls. (): significant () increased late apoptotic/necrotic cells in S-GNPs treated groups compared to untreated controls.
