Abstract

The invention discloses a virus detection system and a micro-fluidic chip thereof. The micro-fluidic chip comprises a liquid storage unit used for storing a liquid used or generated in the detection process, a nucleic acid purification unit communicated with the liquid storage unit and used for purifying a sample liquid to obtain a nucleic acid substance, and an amplification detection unit comprising a main pipeline, a plurality of reaction tanks and a plurality of branch pipelines, wherein the amplification detection unit is communicated with the nucleic acid purification unit through the main pipeline, the reaction tanks are communicated with the main pipeline through the branch pipelines, and the reaction tanks are used for amplifying and detecting nucleic acid substances of differentsample solutions. The multifunctional micro-fluidic chip integrates nucleic acid extraction, nucleic acid purification and nucleic acid amplification and detection. The requirements of all steps of nucleic acid amplification and detection can be automatically met on the premise of one-time sample introduction, and a plurality of reaction tanks are arranged so that amplification and detection of aplurality of sample solutions can be achieved at the same time and the detection efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of nucleic acid detection, in particular to a virus detection system and a microfluidic chip. Background technique [0002] Microfluidic technology mainly relies on the flow of fluid in a very narrow tube. To achieve this goal, researchers need to use chips of different materials to create microfluidic chips of different heights and lengths. At present, the main microfluidic chip materials are mainly concentrated in glass, plastic and other materials. These materials allow scientists to manufacture microfluidic chips through etching and other related techniques. [0003] At present, most of the virus detection chips on the market focus on the detection of the L1 region of the virus. This detection technology can only identify the infection of the virus on a large scale, but it cannot directly indicate which exact virus the patient is infected with. Subtype. At the same time, the detection time of some mi...

Problems solved by technology

[0003] At present, most of the virus detection chips on the market focus on the detection of the L1 region of the virus. This detection technology can only identify the infection of the virus on a large scale, but it cannot directly indicate which exact virus the patient is infected with. Subtype

At the same time, the detection time of some microfluidic chips is too long, resulting in low detection efficiency
