Abstract

The invention discloses a multi-component food safety detection microfluidic chip, comprising a sample pool (1) and 2-8 micro channels; each micro channel includes an inflow channel (2), a reagent storage pool (3), a detection channel (4), a detection chamber (5), an outflow channel (6) and a waste liquid pool (7), wherein the sample pool (1) is connected and fitted to the reagent storage pool (3) through the inflow channel (2), the reagent storage pool (3) is connected and fitted to the detection chamber (5) through the detection channel (4), the detection chamber (5) is connected and fitted to the waste liquid pool (7) through the outflow channel (6), and an included angle between each of the micro channels is 45-180 degrees. The multi-component food safety detection microfluidic chip provided herein is convenient to operate, short in detection time and low in sample consumption and enables simultaneous detection for multiple components with no need repeated sample adding.

Description

technical field [0001] The invention relates to the field of microfluidic chip analysis and food safety rapid detection, in particular to a multi-component food safety detection microfluidic chip. Background technique [0002] With the rapid development of the economy, various agricultural products are widely flowing in the market, and food safety hazards have appeared many times so far. People urgently need to identify harmful ingredients in food through advanced rapid detection technology, so as to provide protection for people's health. Microfluidic chip is a new detection technology platform with high throughput, low sample consumption, simple and fast. This platform can integrate sample pretreatment, reaction, separation and detection process in one chip, and complete the whole analysis process automatically. Widely used in food safety testing. [0003] Colloidal gold rapid detection test strips traditionally used for food safety testing have a small throughput, and ea...
