Abstract
A micro-particle separation apparatus includes a triangular microchannel of which a cross-section is formed in the shape of a triangle and through which a fluid including a plurality of particles flows by a predetermined length; and an outlet that separates particles that have been arranged at different focusing positions in the triangular microchannel, and outputs the separated particles. The triangular microchannel has different focusing positions depending on particle size.
