Abstract

The invention discloses a microfluidic test card, which includes a reaction chamber and a microchannel layer, a microchannel sealing layer and a detection layer, and the microfluidic test card further includes: at least one Liquid storage chamber and pump chamber; each liquid storage chamber and pump chamber and the first liquid storage chamber sealing layer used to isolate the liquid storage chamber and pump chamber between the connected microchannels; and the waste liquid pool, which protrudes from the reaction chamber Cum the microchannel layer and communicate with the reaction chamber. The technical scheme of the invention can greatly reduce the volatility of the liquid, thereby prolonging the storage time of the test card and reducing the loss of the test card.

Description

technical field [0001] The invention relates to microfluidic biological detection, in particular to a microfluidic test card which can be assembled freely, can freely control the flow rate of reaction liquid, and prevent storage liquid from leaking out. Background technique [0002] Due to the development of microfluidic technology using micro-solutions, the use of laboratory-on-a-chip (LOC) or microfluidic chips is proud to break away from the shackles of traditional research experiments, and move further towards commercial applications with more practical value. In the fields of chemistry and biology, microfluidic systems are used more and more, such as the transmission of microfluids, the synthesis of quantitative compounds, sample separation, component analysis and chemical reactions. [0003] At present, microfluidic chips are mainly electrophoresis chips, and the injection of reaction reagents is realized by electrophoresis and electroosmosis. Although the purpose of m...
