Many discoveries in nanoscale science and engineering have been driven in large part by tools which now enable the characterization of fluids inside nanoscale structure. As an electrical engineering point of view, we are trying to implement liquid-based electrical components such as nanofluidic-resistor and -diode and ionic field effect transistor (IFET), etc. Based on these properties, we now revolutionize nanofluidic system as a tool for environment, energy and bio-applications. Through this, we can develop a deeper understanding of the underlying fundamental nanoscale science and electrokinetics. The objectives are to use the micro/nano hybrid device as a model system for characterizing nonlinear electrokinetics and related phenomena including ion concentration polarization (ICP), and to develop novel engineering devices for seawater desalination, fuel cell and bio-sensing applications. The micro/nanofluidic system we have developed is ideally suited to track concentration, flow, and electric field simultaneously, in situ, providing valuable scientific data for this complex, coupled transport behavior. Such data have never been obtained previously, while it would be crucial in studying the ICP phenomena in microscopic detail. At the same time, ICP and related enhanced electrokinetic flow have the potential to be used for developing novel biomolecular preconcentrators and water purification / desalination devices.
