Abstract

The invention discloses a micro-fluidic substrate, a micro-fluidic chip, a micro-fluidic system and a detection method, so that the problems that a micro-fluidic substrate in the prior art is limitedin control precision and a liquid drop which is smaller than the size of a pixel electrode cannot be controlled are solved. The micro-fluidic substrate comprises a transparent substrate, a photosensitive film positioned on one surface of the transparent substrate, and an electric control layer located on one surface, deviating from the transparent substrate, of the photosensitive film; the electric control layer comprises a plurality of control electrodes arranged in an array mode, gate lines located at the gaps between every two adjacent control electrode rows, and source lines located at thegaps between every two adjacent control electrode columns; each control electrode is electrically connected with one corresponding gate line and one corresponding source line through a transistor; and the photosensitive film is configured to generate a photo-generated built-in electric field when the photosensitive film is irradiated by the light incident on the substrate side of the transparentsubstrate.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic substrate, a microfluidic chip, a microfluidic system and a detection method. Background technique [0002] Microfluidics is a technology that precisely controls and manipulates micro-scale fluids. Through this technology, researchers can integrate basic operating units such as sample preparation, reaction, separation, and detection into a centimeter-scale chip. This technology is generally used in the analysis process of trace drugs in the fields of biology, chemistry, pharmacy, etc. It mainly involves the transportation and mixing of trace reagents. This technology is of great significance to the development of fields such as biomedicine, drug diagnosis, food hygiene, environmental monitoring and molecular biology. [0003] However, the microfluidic substrate in the prior art has the problem of limited control precision, and cannot manipulate droplets smal...
