A) The pattern of AO/ EtBr staining of B16-F10 cancer cell line and L929 normal cells treated using CAP, nZVI, and combination treatment. Viable cells are green in color while dead cells are red. B) Annexin V/PI flow cytometry analysis of the B16-F10 and L929 cells after harvesting by trypsinization. The graph represents the percentage of live cells, early and late apoptosis, and necrosis.
