A microfluidic apparatus includes a filter unit including an entrance, a separation portion in which eluant contacts microparticles to separate a target substance bound to surfaces of the microparticles from the microparticles, an exit, and a filter blocking leakage of the microparticles through the exit, a fluid supply portion selectively supplying the eluant and a sample solution including the microparticles capturing the target substance, to the filter unit, and a resupply unit supplying the eluant passed through the filter unit back to the filter unit. |
