Abstract

The invention discloses a microfluidic chip and relates to the technical field of microfluidics. The microfluidic chip comprises a stock solution tank, M incoming liquid channels, and a chip substrate; the chip substrate comprises a substrate base plate, an electrode array layer, an insulating drain layer, and a microfluidic channel layer; the electrode array layer comprises a plurality of transfer electrodes and M reaction structures; every transfer electrode is connected with a driving circuit; each reaction structure comprises X reaction electrodes; the X reaction electrodes are positionedaround the transfer electrode N in a direction parallel to the substrate base plate; every reaction electrode is connected with the driving circuit; the driving circuit is used for providing a voltageto the transfer electrode N and the reaction electrodes around the same such that a drop is split into X droplets which move to the reaction electrodes respectively. Drop injection difficulty can bedecreased, the quantity of the incoming liquid channels can be decreased, layout space can be utilized effectively, the cost can be reduced, drop transfer speed is never affected, time can be saved, and efficiency can be improved.
