Morphological assessment of MCF-7 cells stained with acridine orange (green) and propidium iodide (red). Cells are incubated with or without α-Fe2O3 at various concentrations for 24 h. Cells with intact membrane and stained green indicate viable cells; cells that are stained orange represent secondary necrotic or late apoptotic cells containing fragmented DNA (magnification 100x, scale bar 20 μm).
