Intermolecular Transfer of Radiation Energy at 77°K: An ESR Study of Irradiated Mixtures of Macromolecules and Oxidized Penicillamine

Radiation Protection of Hyaluronic Acid in the Solid State

“…In this way, for a-1,4 cycloamyloses (2, 3), amylose (4), and recently, heparin (5) complexed with certain organic molecules, it has been demonstrated that energy transfer operates in these solidstate aggregates. Using other methods, energy transfer effects were demonstrated in molecular mixtures of penicillamine and sephadex (6,7). Energy transfer has been generally considered in relation to the radiation decomposition and inactivation of biological macromolecules (8,9).…”
