Cell survival after PDT. LM3 cells were incubated with 2.5 μM or 5 μM of the photosensitiser during 3 h or 24 h and afterwards, PDT was performed. Cell viability was evaluated by the MTT assay, as the percentage of photosensitiser-exposed non-irradiated cells. Control: cells exposed to the vehicle at the maximum concentration employed and light-treated. Error bars are the standard deviation for three independent experiments
