A 2D Electric Double Layer Model for Biological Nanochannels

We developed a 2D electric double layer model for biological nanochannels based on the linearlized Poisson-Boltzmann equation with arbitrary surface potential. Time dependent adsorption kinetics was used in the model to examine the variation of electric double layer distribution and compare with that from the classical model. Based on the 2D model, EDL interaction for heavily patched arbitray surface potential was found to be much weaker in such biological nanochannels. Channel end effects are also found to be significant and not negligible.
