Discrimination of the cellular responses towards PDT. Measurement of the overall viability at early versus late time points following illumination (a) allows for calculation of a difference curve (b) and estimation of the dose ranges which predominantly induce cellular survival, apoptosis, and necrosis (c). PS: photosensitizer. For details on interpretation see text.
