Cell viability of MLH/Ce6 depending on pH conditions. CT-26 cell viability in (a) pH 7.4 or (b) pH 6.4 in the absence or presence of laser irradiation (laser power = 2 J, incubation time = 4 h), (c) CLSM image of the Live&Dead assay. The live cells were stained green. The dead cells were stained red. Scale bar is 100 μm. d DCFDA assay of MLH/Ce6 (laser power = 2 J, concentration of Ce6 = 1 µg/mL)
