HCT 116 human colorectal carcinoma cells incubated for 24 h with PL PAG 1 (10 μM) and irradiated at 710 nm (70 fs pulses, 80 MHz repetition rate, 2.0 mW/cm2). Generation of photoacid induced by 2PA promoted necrosis in HCT 116. Residual PAG 1 fluorescence illustrated PAG uptake. Cells were unaffected by non-irradiated PAG or irradiation w/o PAG. Scale bar 50 μm.
