Near-Infrared Two-Photon Excitation of Protoporphyrin IX: Photodynamics and Photoproduct Generation

The spectroscopy and photochemistry of protoporphyrin IX in ethanol and in Triton X-100 micelle solution have been examined using near-infrared two-photon excitation (TPE). TPE will allow photodynamic therapy with highly localized light dosage. We have determined that the photochemistry subsequent t...

Summary:The spectroscopy and photochemistry of protoporphyrin IX in ethanol and in Triton X-100 micelle solution have been examined using near-infrared two-photon excitation (TPE). TPE will allow photodynamic therapy with highly localized light dosage. We have determined that the photochemistry subsequent to TPE is very similar to that found for one-photon excitation. Moreover, the photoproducts observed possess very intense TPE fluorescence spectra, which allows their detection at low relative concentrations.
