Abstract

Electroosmotic flow is a popular transport mechanism used in nanofluidic systems, where the critical channel dimension can approach the size of fluid molecules. Understanding the scaling behavior of the electroosmotic transport is important for the design and optimization of nanofluidic systems. Here we report on the scaling of electroosmotic flow and ionic conductivity in negatively charged slit nanochannels by using continuum and atomistic simulations. We show that the deviation of the transport properties of the interfacial fluid from its bulk values and the molecular nature of water and ion can influence the scaling behavior of the electroosmotic transport in confined nanochannel significantly.
