Irradiation of an aqueous solution of hematoporphyrin causes the formation of the stable photoproduct which may play an important role in cancer therapy. The spectra and kinetic characteristics of the absorption changes of hematoporphyrins and their photoproducts were measured by a picosecond pump a

Inhomogeneous broadening of visual pigment spectra may be due. in part, to the known dynamic conformational properties of protein molecules. As a consequence, the blue-shifted species formed by long-wavelength irradiation of rhodopsin at very low temperatures could be an artefact arising from photos
Haematoporphyrin derivative (HpD) photoproducts are formed in aqueous solutions during light exposure in the presence of oxygen. The evaluation of the fluorescence decay of the photoproduct-enriched HpD solution shows an increase in the short-lived components, especially about 2 ns, in comparison wi
