Fluorescence images (400x magnifications) of DAPI and Rh-123 stained (A) MDA-MB-231 and (B) MCF-7 cells treated with drugs and different nanoformulations for 48 h. The treated both cancer cells showed abnormalities in nucleus as well as mitochondrial membranes indicating the induction of apoptosis and loss of mitochondrial membrane potential (Δψm).
