Photosensitized Singlet Oxygen Production And Photophysical Properties Of Cationic Porphyrin - Transferrin Complexes

Photophysical properties of new tumor targeted photosensitizers based on cationic porphyrins and human transferrin were investigated. It was demonstrated that incorporation of the porphyrins into the protein causes slight changes of the photophysical properties of the photosensitizers. The kinetics of singlet oxygen luminescence photosensitized by porphyrin-transferrin complexes were studied.
