The Effect of Water Polarization and Hydration on the Properties of Charged Lipid Membranes
We describe the physical properties of a planar interface between an electrolyte and a charged lipid membrane. The model differs from the usual Gouy-Chapman-Debye-Huckel theory for electrolytes in that the dipolar nature of the water molecules and the hydration force at the interface are explicitly included. The dielectric constant and potential of the electrolyte are calculated as functions of distance from the interface for surface charge densities corresponding to anionic lipid bilayers. Finally we look at the electrostatic properties of two bilayers separated by a distance d.
