Abstract

The ion and fluidic transport in the nanopore system is investigated via a multi-physical modeling of the electrostatic, nanofluidic and ion motion properties. We solve a series of coupled equations including Poisson, Navier-Stokes and Nernst-Plank descriptions for the system. We quantitatively investigate the relation between the induced electroosmotic flow in the presence of nanopore wall surface charges and the applied cross-pore voltage. Such electrical-to-mechanical energy conversion may find potential application in nanoelectro-mechanical devices (NEMS).
