The Electrostatic and Electrokinetic Properties of Biological Membranes: New Theoretical Models and Experimental Results
Gouy (1) and Chapman (2) formulated the concept of the diffuse double layer by combining the Poisson and Boltzmann equations to describe the profile of the electrostatic potential in an aqueous phase adjacent to a charged surface. Stern (3) modified this concept by introducing the possibility that ions could bind to the surface. The Gouy-Chapman-Stern theory of the diffuse double layer describes adequately the electrostatic potential adjacent to a phospholipid bilayer: as the theory requires, the charges on a negative phospholipid are located in a plane at the bilayer surface.
