Cytotoxicity of the ultra-small Au-NPs on human cancer cells against human cancer cell lines (Caco-2, HepG-2 and MDA-MB 231). (A) The percentage of growth inhibition of each cancer cell line after 24 h, 48 h, and 72 h incubation. (B) Morphological alterations of Au NPs-treated cancer cells in comparison to the untreated control cells (Magnification × 200). All data are expressed as mean ± SEM.
