Abstract

The invention discloses a microfluidic chip and a driving method thereof, comprising: a base substrate and an electrode layer located on one side of the base substrate; the electrode layer includes a first electrode and a second electrode insulated from each other; at least one droplet shunt The droplet splitting unit includes at least one first electrode, two second electrodes, and a first partition; the first partition and the electrode layer are located on the same side of the substrate, in a direction perpendicular to the plane where the substrate is located Above, the height of the first partition is greater than the height of the first electrode, and it is greater than the height of the second electrode; in the same droplet splitting unit, the two second electrodes are arranged on the same side of the first electrode along the first direction, and the second electrode A partition is located between the two second electrodes. The invention can quickly and accurately split the droplet.

Description

technical field [0001] The present invention relates to the field of microfluidics, and more specifically, to a microfluidics chip and a driving method thereof. Background technique [0002] Micro-fluidic technology is a technology whose main feature is the manipulation of fluid in the micron-scale space. This technology has intersected with various disciplines such as chemistry, biology, engineering and physics, showing a wide range of application prospects. [0003] When microfluidic technology is applied to biological detection or chemical detection, by setting several to hundreds of sample detection areas on the microfluidic chip for detection, with the increasing demand for the accuracy and comprehensiveness of detection data , the demand for the number of detection samples is increasing. In order to improve the detection efficiency and reduce the detection cost, the detection droplets need to be separated in the microfluidic chip. However, the existing microfluidic c...
