Photoemf at a Single Membrane-Solution Interface specific to Lipid Bilayers containing Magnesium Porphyrins

Nature New Biology volume 240, pages 154–155 (1972)Cite this article

Abstract

THE study of ionic effects in Rudin-Mueller bimolecular lipid membranes containing ionophoric agents has increased the understanding of ion transport across biological membranes. The study of photoreactions in these membranes containing light sensitive chromophores promises to be equally informative. Several teams have reported on such studies1–9, mostly using continuous light. The mixture of photoemf and conductance changes, however, is difficult to separate, and it is not known whether the photoresponses originate from the thin bimolecular region or from the thick annular region (Plateau-Gibbs border) of the membrane. We report here evidence that fast photoemfs across a single interface of such membranes are specific to the bilayer.
