The effect of MZF@sil@Au-DMSA, MZF@sil@Au-TG, MZF@sil@Au-MUA, or MZF@sil@Au-MTAB on the (a) proliferation and (b) viability of MCF-7 cells. Changes in the proliferation and viability were monitored using the trypan blue exclusion test 48 h after the treatment. Results are shown as mean ± SD from three experiments; the asterisk marks results significantly different from the control (p ≤ 0.05). Cells treated with 1 µM doxorubicin and sterile deionized water were used as a positive and negative control, respectively.
