Abstract:
1. A microfluidic-chip comprising: an inflow port wherein fluid is supplied, a multi-channel, the multi-channel having a plurality of microchannels arranged in parallel with each other, and wherein electric potentials occur between both ends of an inlet and an outlet of the microchannels by streaming potential when the fluid passes through the microchannels, a distributor located between the inflow port and the multi-channel, wherein the distributor uniformly transfers fluid from the inflow port flow into the multi-channel, a collector collecting fluid that flows out through the multi-channel, an outflow port from which the fluid in the collector flows out, and a pair of electrodes, the electrodes positioned respectively in the distributor and in the collector, and which connects to an external circuit in order to use the electric potential, wherein the inflow port is located at the inlet side of the microchannel positioned in the one side of the multi-channel, the outflow port is located at the outlet side of the microchannel positioned in the other side of the multi-channel, and wherein the cross-sectional area of the distributor decreases from the one side located next to the inflow port to the other side, and the cross-sectional area of the collector also decreases from the one side located next to the outflow port to the other side.
