Channel filter having surface topology for filtering micro particles and method for manufacturing same

摘要

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.

主权项

1. A channel filter for separating various sized microparticles, wherein the channel filter has a surface topology so that the microparticles are trapped according to their sizes and the microparticles that are moved by a capillary action are sequentially separated according to their sizes,
wherein the surface topology has a curvilinear shape, wherein the surface topology comprises a plurality of individual topologies having various heights corresponding to the sizes of the microparticles in a length direction, from an inlet of the channel through which the microparticles are loaded, to an outlet of the channel through which the microparticles are discharged, wherein the surface topology also has various intervals between adjacent individual topologies corresponding to the sizes of the microparticles in a width direction perpendicular to the inlet and the outlet of the channel, and wherein individual topologies have a curvilinear shape.
