Dose-dependent phototoxicity of free IR700, 8PEG-IR700 and RGD-8PEG-IR700 in A375 cells. Alamar Blue assay was performed after A375 cells were treated with free IR700, 8PEG-IR700 and RGD-8PEG-IR700 followed by light irradiation (Right). A375 cells that were only treated with PSs served as controls (Left). N = 4.
