Abstract

This paper presents a critical phenomenon involving a sharp increase in conductance at a critical value of the electric field applied to a bilayer lipid membrane (BLM). By varying the density and the sign of the charge on the BLM at various pH values, the critical potential changes. These changes are related to the variations in the surface potential and indicate that the reorganization of the external polar surface under the action of the electric field always starts on the side in which the electric field is directed from the inner to the outer surface of the monolayer.
