| titleOfInvention | Pesticide residue and nitrite detection device and method based on code scanning type paper chip |
| abstract | The invention relates to a device and a method for detecting pesticide residues and nitrite based on a code scanning type paper chip, which adopts a micro-fluidic technology and an image processing technology to identify, detect and record the pesticide residues and nitrite harmful substances, a multilayer micro-fluidic paper chip is arranged in a detection cavity of a heatable chip and consists of five layers which are stacked from top to bottom and are glued together, a chip bar code detection area is arranged on each layer, a dropper drops the mixed liquid into a chip injection port dropwise, the chip bar code detection areas on each layer show different colors according to the components of the sample mixed liquid, an intelligent mobile device images and scans the color development result of the multilayer micro-fluidic paper chip to obtain the detection result, the inhibition principle of organic phosphorus pesticides on acetylcholinesterase and the diazo coupling reaction of aminobenzenesulfonic acid and N-1-naphthyl ethylenediamine under an acidic condition are applied, the system integrates automatic sample introduction, intelligent heating, reaction, color development and result analysis, recording and processing. |
