Quantitative detection system, and preparation method and application method for mercury ion detection chip

Abstract

The invention provides a quantitative detection system, and a preparation method and an application method for a mercury ion detection chip. The quantitative detection system comprises the detection chip and a forehead thermometer. The detection chip comprises a sample cell, a mercury ion responsive hydrogel micro-valve, a filter screen and a heating groove, the bottom of the sample cell is provided with a micropore, the lower end of the micropore is provided with a filter screen, a mercury ion responsive hydrogel coats the part of the filter screen at the micropore so as to form the mercury ion responsive hydrogel micro-valve, the lower end of the micropore is communicated with one end of the heating groove, the heating groove is filled with a porous capillary material, and the porous capillary material at the other end of the heating groove is filled with NaOH powder. According to the invention, the quantitative detection system overcomes the disadvantages of complex operation, high cost and the like of traditional detection methods on the basis of a heating method and has the characteristics of high sensitivity, simple operation and low cost when applied to detection.

Description

technical field [0001] The invention relates to a quantitative detection system and a method for preparing a mercury ion detection chip therein, specifically comprising a quantitative detection system, that is, a system for quantitative detection of a test object through the principle of heat generation and heat signal release by material dissolution. And using the preparation method, a heating chip for detecting mercury ions in aqueous solution was successfully prepared. Background technique [0002] At present, the methods of in vitro (clinical) diagnosis mainly include: one is to use the large-scale instruments and equipment in the analysis laboratory supporting the hospital; High sensitivity, but with the increasing aging of the population, relying solely on hospital laboratory centers will greatly increase health costs. The latter is simple, fast, and low-cost, and can realize home-based analysis and diagnosis. [0003] At present, POCT analysis and detection are mainl...
