Microfluidic device, microfluidic system and method for controlling microfluidic test device

Abstract

A microfluidic device, a microfluidic system and a method for controlling a microfluidic test device are provided. The microfluidic device includes a rotatable platform including 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 electrochemically induced 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 disposed in the reaction chamber and configured to capture the target material; 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; and a plurality of channels connecting the chambers.
