Abstract

The invention belongs to the field of food safety and discloses a device for detecting a pesticide based on automatic color change through utilization of a nucleic acid probe. A camera I, a camera II,a lighting system and a color change detection unit are mounted on an observation part holder. A control part is mounted in a control part holder. A lead storage battery is connected with a motor control board and raspberry pie and supplies power. The motor control board is in power connection with the raspberry pie, an electromagnetic valve, a relay and a water and a water and air dual-purpose pump. The supplies power to the relay, the electromagnetic valve and the water and air dual-purpose pump. The camera I and the camera II are connected with the raspberry pie through utilization of a USB cable. The camera I is used for observing a state of test film. The camera II is used for observing a color of reference film. The device is compact in structure. Color change time is short. Throughutilization of a flow channel designed by a color change unit, a color change period is reduced to about 50s. Photonic crystal film for modifying different nucleic acid aptamers can be replaced. Thedevice is wide in adaptability.

Description

technical field [0001] The invention belongs to the technical field of food safety, in particular to a device for detecting automatic discoloration of pesticides by nucleic acid probes. Background technique [0002] Pesticides play an important role in ensuring the yield and quality of crops, but improper handling in the process of production, transportation, storage and use will cause a series of incidents such as pesticide poisoning, pesticide residues, food safety, etc., which pose a threat to human health and the ecological environment. serious threat. At the same time, excessive pesticide residues will also affect the trade of agricultural products. Now countries around the world attach great importance to the problem of pesticide residues, and the pesticide residue standards of agricultural and sideline products are gradually increasing. China’s agricultural and sideline product export trade is also facing severe challenges. Therefore, the detection of pesticide residu...
