Novel microfluidic device

The invention discloses a novel microfluidic device, which comprises a supporting base, a microfluidic box body, a fluorescence signal detector I and a fluorescence signal detector II, wherein supporting legs are arranged below the supporting base, and a controller is arranged on one side above the supporting base. According to the invention, by arranging a plurality of reaction holes and detection holes, a micro-fluidic rotating disc can be controlled to directionally rotate at a fixed angle by rotating a servo motor, so that the detection work of the contents of a plurality of items can be completed at one time so as to save time and labor; through a quickly-assembled clamping groove, rapid mounting and dismounting operation of the micro-fluidic rotating disc on the rotary supporting base can be realized, so that the subsequent cleaning work on the micro-fluidic rotating disc is facilitated, and practicality and convenience are achieved; and by arranging a magnetic bead fluorescenceenhancement liquid in a d
