Claim Text:
1. A microfluidic device comprising a rotatable platform, wherein the platform comprises: a sample chamber to which a sample is supplied; a first reagent chamber; a first capture conjugate disposed in the first reagent chamber and configured to capture a target material contained in the sample; a second reagent chamber; a signal material disposed in the second reagent chamber and configured to be induced to have electrochemical activity by the first capture conjugate; a reaction chamber providing an area in which a biochemical reaction between the sample and the signal material supplied occurs when the platform rotates; a second capture material immobilized within the reaction chamber and configured to capture the target material such that the target material and the first capture conjugate are immobilized within the reaction chamber; a detection chamber separated from the reaction chamber, the detection chamber comprising a detector configured to detect an electrochemical signal generated by the signal material which moves to the detection chamber from the reaction chamber; and a plurality of channels connecting the chambers.
