Control of ion transport across bilayer lipid membranes by adjustment of surface charge associated with phase domain structures

Interest continues in the use of immobilized lipid membranes of mixed lipid composition to prepare chemically modified electrodes. Fundamental investigations of the structure and mechanism of the analytical function of such systems are scarce. In this work ion conductivities of bilayer lipid membranes formed from mixtures of egg phosphatidylcholine and dipalmitoylphosphatidic acid were evaluated to determine the effect of surface charge and …
