ABSTRACT:
Disclosed is a disk based platform for separating and detecting cells that are labeled with immunomagnetic beads. A disk-like carrier board forms therein at least one flow channel structure, which includes an inner reservoir for receiving a sample fluid, an outer reservoir, and a plurality of micro flow channels arranged between and in fluid communication with the inner and outer reservoirs. When the disk-like carrier board spins, cells labeled with immunomagnetic beads are attracted by a magnetic attraction unit that is arranged above the disk-like carrier board and adjacent to the inner reservoir to thereby remain in the inner reservoir, and cells that are not so labeled are acted upon by a centrifugal force induced by the spinning of the disk-like carrier board to flow with the sample fluid from the inner reservoir through the micro flow channels into the outer reservoir.
