Caspases spectrophotometric analysis of K562 cells after being treated with S-GNPs for 24 and 48 h, respectively.

Caspase	Cells %
	Control/24 h	Treated/24 h	Control/48 h	Treated/48 h
Caspase-3	0.055 ± 0.035	0.15 ± 0.03	0.077 ± 0.041	0.20 ± 0.009
Caspase-9	0.061 ± 0.071	0.17 ± .005	0.079 ± 0.007	0.22 ± 0.0055

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 with Tukey’s- test. (): significant () increase of apoptotic cells in S-GNPs treated groups compared untreated controls.
