Abstract

The invention discloses a microfluidic chip, which relates to the field of microfluidic technology. The microfluidic chip includes a raw liquid pool, M liquid inlet channels, and a chip substrate; the chip substrate includes: a substrate substrate, an electrode array layer, and an insulating hydrophobic layer. , the microfluidic channel layer, the electrode array layer includes a plurality of transfer electrodes and M reaction structures; each transfer electrode is connected to a drive circuit, each reaction structure includes X reaction electrodes, in a direction parallel to the substrate substrate, The X reaction electrodes are respectively located around the Nth transmission electrode, and each reaction electrode is connected to a driving circuit, and the driving circuit is used to provide voltages to the Nth transmission electrode and the surrounding reaction electrodes respectively, so that the droplet is decomposed into X small The droplets move to the reaction electrodes respectively. The invention can not only reduce the difficulty of liquid droplet injection, but also reduce the number of liquid inlet channels, effectively utilize the layout space, save costs, and not affect the transmission speed of liquid droplets, which can save time and improve efficiency.
