Photosensitization in biopolymers.
— The energetics of photodynamic action is discussed in terms of oxidation potentials of sensitizing dye intermediates. The results are compared with rate constants and quantum yields for photodynamic oxidation of iodide ion, aromatic amino acids, and lysozyme in the presence of eosin Y. The role of dye binding is discussed for the eosin-human serum albumin complex.
