A micro fluidic device to realize the new fluid separation method, in which both high concentration and high yield can be achieved by constructing a network of numerous limited-performance separator elements, was designed and fabricated for the purpose of proof of concept. A hexagonal separator unit driven by potential gradient was proposed, enabling simultaneous fabrication of the large number of separator units and their connection required to obtain the desired concentration profile. A prototype device consisting of 36×360 separator units was fabricated by MEMS technology with silicon and glass substrates. A thermophoretic separation experiment using fluorescent polymer beads/water dispersion was successfully performed by the developed device.
