Citrate-capped AuNPs exert cytotoxic effects in MDA-MB-231 cells through the induction of oxidative stress. (A) Zeta (Average size) of citrate-capped AuNPs (B) Zeta potential of citrate-capped AuNPs (C) TEM image of citrate-capped AuNPs (D) MTT assay of citrate-capped AuNPs in MCF-10A cells for 24 h (E) MTT assay of citrate-capped AuNPs in MDA-MB-231 cells for 24 h (F) DCFDA assay of citrate-capped AuNPs at concentrations of 100, 250 and 500 μg/mL in MDA-MB-231 cells respectively for 30 min. Results shown are representative of three different experiments. All values were expressed as mean ± S.E.M. *p < 0.05, **p < 0.01, ***p < 0.001 significant vs control.
