  • Patent number: 7045117
    Abstract: Palladium-substituted Bacteriochlorophyll derivatives are administered to a subject suspected of having a tumor and the patient is then irradiated and the fluorescence of the suspected area is measured. A high fluorescence indicates a tumor site. A preferred derivative is Pd-Bacteriopheophorbide a.
