Pesticide residue detection micro-fluidic chip with pre-stored reaction reagent

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...
