Bilkent Üniversitesi Photoinduced cytotoxicity Fluorescence microscope images of acridine orange (AO) and propidium iodide (PI) stained K562 cells, incubated in full medium with 500 nM sensitizer 3 in dark (the middle panel); irradiated with red LED at 625 for 4 hours followed by 20 hr incubation in dark at 37 oC in the presence of 500 nM sensitizer 3 (right panel); and incubated in dark for 24 hr (left panel). Live cells were preferentially stained with AO (green) and dead cells with PI (red) due to increased cellular permeability.
