Problems solved by technology

When microfluidic technology is applied to gene detection, there are thousands of positions in high-throughput microfluidic droplets. In the prior art, microscopes or high-precision cameras cannot quickly and accurately identify which droplet participates in the reaction. , that is, it is impossible to judge the biochemical reaction between the sample and the reaction enzyme, and it is impossible to identify the gene type correspondingly

Abstract

The invention discloses a chip substrate and a microfluidic chip, comprising: a base substrate and a transparent electrode layer located on one side of the base substrate, the transparent electrode layer includes a plurality of driving electrodes arranged in an array, and the driving electrodes are used to drive The movement of the droplet; a plurality of coding parts located between the base substrate and the transparent electrode layer, the coding parts and the driving electrodes are arranged in one-to-one correspondence, and the vertical projection of the coding part on the plane where the substrate is located is located at the corresponding driving electrode. Substrate In the vertical projection of the plane where the substrate is located. By will. The invention can quickly and accurately determine the position of the droplet.

Description

technical field [0001] The invention relates to the field of microfluidics, and more specifically, to a chip substrate and a microfluidics chip. 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] At present, in the process of controlling the flow of micro-droplets using microfluidic technology, it is necessary to position the micro-droplets. Since the size of the micro-droplets is at the micron level, a microscope or a high-precision camera is used to determine the position of the micro-droplets. When microfluidic technology is applied to gene detection, there are thousands of positions in high-throughput microfluidic droplets. In the prior art, microscopes or high-precision cameras cannot quickly and accurately iden...
