Cytotoxic effect of nanoparticles (CurtoCK-AuNPs) and C. proimmune K3 (CP) on normal and cancer cells. A HaCaT human keratinocytes. B RAW264.7 murine macrophage. C AGS human gastric cancer cells. The cell viability was evaluated using MTT assay. D The microscopic images (magnification ×100) of stained AGS cells treated with CurtoCK-AuNPs for determination of colony formation. Medium alone and cisplatin (50 μM) were used as negative (NC) and positive (PC) controls, respectively. The colony formation was evaluated using crystal violet staining and their quantified results. The asterisks on each column indicate significant difference between NC and each sample. *p < 0.05; **p < 0.01, ***p < 0.001. ns, not significant
