Western blot analysis on Au@ginsenoside Rh2 NPs caused expression of caspase group (caspase-3, 8, 9) which related to apoptosis of cancer cells (A, B) and the relative gray intensity (vs internal reference) of caspase-3, 8, 9 with different concentrations of Au@ginsenoside Rh2 NPs in A375 cells (C, D). Results indicated the apoptosis of A375 cells has been certainly induced after treating with Au@ginsenoside Rh2 NPs (*p < 0.05 vs control group, #p < 0.05 vs control group, consider the two bands of cleaved caspase-3 as one group)
