Abstract

In many research groups, ion concentration polarization (ICP) phenomenon has been used in many application fields, such as sample preconcentration, micro mixer and desalination. Here, we present a new continuous-flow separation method based on the ICP. The configuration of this system is similar to that of conventional nanofluidic concentration device, so that electrical force takes place near the nanojunction when applying external voltage. Using the force, we performed separation of particles depending on their sizes. This research might be very meaningful in developing an integrated separation device which can separate various kinds of samples in one chip.
