Comparative characterization of the cellular uptake and photodynamic efficiency of Foscan® and Fospeg in a human prostate cancer cell line

The use of the PEGylated liposomal formulation of m-THPC resulted in the improvement of its intracellular uptake and the enhancement of its photodynamic activity. Fospeg, compared to Foscan®, proved to be a more advantageous photosensitizer for photodynamic therapy.
