Theory of the Effect of Surface Active Agent on the Electric Conductance of Lipid Membranes. II

Abstract

A theoretical analysis of the ionic transport across a membrane is given in order to explain the experimental fact that the ionic conductivity through the artificial bimolecular layer of lipid molecules increases with the concentration of either cationic or anionic surface active agent in the electrolyte solutions on both sides of the membrane.
The adopted model is the thin symmetric membrane with electric double layers whose charges are affected by the physical adsorption of the agent.
This model is not only more realistic as a model of the lipid membrane than that used in the previous paper but also able to explain well the experimental results.
