Our previous study has shown a prolonged retention and accumulation of Zn-pheophorbide a, a water-soluble derivative of chlorophyll a, in tumor tissue (Szczygiel et al. [19]).This prompted us to further evaluate the phototherapeutic potential of this photosensitizer of excellent physicochemical properties.
