[0016] Specific implementation plan

[0017] The following examples will further illustrate the present invention, but do not limit the present invention.

[0018] Such as figure 1 As shown, the pesticide residue detection microfluidic chip for pre-stored reaction reagents provided by the present invention includes a sac pool, a sac, a sample pool, a microfluidic channel, two reagent pools and reagents.

[0019] When testing, only need to put the quantitative sample to be tested into the chip sample cell 3, close the sample chamber sealing cover 10, release the extract 6 in the liquid bag, and connect the vent 9 to the external pressure regulating valve to make the internal chamber of the chip and the atmosphere generate The pressure difference drives the flow of the liquid. The extraction liquid enters the sample cell 3 to mix and extract the sample to be tested, and then the mixed liquid enters the reagent cell 4, fully mixes with the pre-stored reagent 7 and reacts into the reagen...

Abstract

The invention provides a pesticide residue detection micro-fluidic chip with a pre-stored reaction reagent. The pesticide residue detection micro-fluidic chip is characterized by comprising a micro-fluidic channel, a liquid sac pool, an extracting solution sac, a sample pool, a sample pool cover, a plurality of reagent pools and bio-reagents stored in the reagent pools. During detection, a to-be-detected sample just needs to be put into the sample pool of the chip, a reagent solution such as an extracting solution, an enzyme liquid, a color developing agent solution or a primer solution does not need to be prepared. The chip is concise to operate and suitable for field detection of pesticide residues and has an extremely important application value.

Description

technical field [0001] The invention relates to the field of microfluidic chip analysis, in particular to a microfluidic chip used for on-site detection of pesticide residues. Background technique [0002] At present, microfluidic chip analysis technology has been applied to the rapid detection of organic pesticide residues due to its significant advantages such as miniaturization, integration, high throughput, and low cost. However, in the on-site detection of pesticide residues, it is still necessary to carry or configure various reaction reagent solutions such as extraction solution, enzyme solution, chromogenic reagent solution, and substrate solution, and then manually transfer various solutions to the microfluidic chip to increase the analysis time. The operation intensity of personnel, and the solution is inconvenient to carry; the configuration process is lengthy, which can no longer meet the needs of rapid detection of pesticide residues, and has become a bottleneck...
