Abstract
The present invention provides a microfluidic structure for sorting targeted substances. The microfluidic structure includes: an inlet portion having at least one fluid input port; an outlet portion having a plurality of fluid output ports; a first annular flow channel communicated with the inlet portion at the upstream end and rotatably extended; and a second annular flow channel communicated with the downstream end of the first annular flow channel at the upstream end, communicated with the outlet portion at the downstream end and rotatably extended. The first annular flow channel and the second annular flow channel are connected in series according to an S-shaped track, so that the outer side wall of the first annular flow channel is continuously connected to the inner side wall of the second annular flow channel. The cross-sections of the first annular flow channel and the second annular flow channel have a height difference.
