A Variable Nano Capacitor Behaved Arising from Lipid Bilayers of DMPC

Abstract

Bio-membranes are thin capacitors and because the membrane has a dynamic behavior and in the various positions has different area and thickness, the capacitance of the membrane is not fixed and causes a variable capacitor. In this study, we have shown the model of a microscale dielectric membrane capacitor including DMPC structures. We have shown that Quantum effect has appeared in a small free space of the membrane thickness due to number of phospholipids layers. In addition, we have specifically investigated the quantum and coulomb blocked effects of different thickness. Furthermore, the electron density profile models, electron localization function (ELF) and local information entropy have been applied as a formal way to studies the interaction of protein with lipid bilayers in cell membrane.
