Glass, James C., G. Graf, H. Costabal, D. H. Ewert and L. H. English, “Positrons In Bimolecular Systems II: Membranes,” Proceedings of the Sixth International Conference on Positron Annihilation, sponsored by the International Union of Pure and Applied Physics and American Physical Society, University of TX at Arlington, pp. 930-931. April. 1982.
Pickoff-annihilation parameters, as related to the free volume model, are shown to be indicators of structural fluctuations in membranes and membrane bound proteins. Nitrous oxide anesthetic induces lateral rigidity in a membrane, and an anesthetic mechanism is suggested. Conformational changes of (Na+,K+)ATPase in natural membrane are observed with ATP and Mg-ion binding. New positron applications to active transport and photosynthetic systems are suggested.
