Abstract
A centrifugal force-based microfluidic device for the detection of a target biomolecule and a microfluidic system including the same are provided. The device includes a body of revolution; a microfluidic structure disposed in the body of revolution including chambers, channels connecting the chambers, and valves disposed in the channels to control fluid flow, the microfluidic structures transmitting fluid using centrifugal force due to rotation of the body of revolution; and beads disposed in the microfluidic structures, the beads having capture probes on the surfaces thereof which are selectively bonded with target protein; and a detection probe disposed in the microfluidic structures and selectively bonded to the target protein, and which includes a material required to express an optical signal, wherein the microfluidic structure mixes the beads, biological samples, and the detection probe to react and washes and separates the beads after the reaction.
