[Theory of hydrophobic ion adsorption in bilayer lipid membranes taking into account their lateral interaction and charge discreteness].

A relationship was calculated between the number of adsorbed hydrophobic ions and the potential created by them in BLM and concentrations of these ions in solution, ionic strength in solution, the value of the membrane charge and the potential dipole shift on the BLM surface. It was assumed in the model under consideration that the ion adsorption plane was located at some depth inside the membrane, the discrete nature of the ions, their possible lateral interaction and existence of various adsorption centres in the membrane being taken into account.
