Abstract
Disclosed is a channel filter for separating microparticles, and more particularly to a channel filter which can easily separate a sample having various sized microparticles by using a surface topology. In the disclosed channel filter, a topology having an upward/downward reference height from a sample inlet to an outlet is continuously or discontinuously formed, and thus it is possible to efficiently separate microparticles from a sample liquid.
