Embodiment 1

[0026] A preparation method of a novel colorimetric supramolecular sensor for detecting amphetamine-type drugs of the present invention comprises the following steps: constructing and obtaining by using inducible compound 3A and PP6@AgNPs colloidal solution as raw materials, and preparing a colorimetric supramolecular sensor for detecting amphetamine-type drugs A novel colorimetric supramolecular sensor.

[0027] A preparation method of a novel colorimetric supramolecular sensor for detecting amphetamine drugs of the present invention comprises the following steps: (1) preparing a PP6@AgNPs colloidal solution:

[0028] Add 1 mL of PP6 solution with a concentration of 20 μM to 2-20 mL of deionized water, and add 200 μL of AgNO with a concentration of 10 mM to the prepared mixed solution 3 solution, then add 20 μL of 0.1 M NaBH 4 solution; react the mixed solution under stirring for 5 minutes to obtain a PP6@AgNPs colloidal solution; as figure 1 As shown, the TEM images of PP6...

Embodiment 2

[0033] The difference between embodiment 2 and embodiment 1 is:

[0034] In step (1), prepare PP6@AgNPs colloidal solution:

[0035] Add 1 mL of PP6 solution with a concentration of 40 μM to 5 mL of deionized water, and add 200 μL of AgNO with a concentration of 10 mM to the prepared mixed solution 3 solution, then add 20 μL of 0.1 M NaBH 4 solution.

Embodiment 3

[0037] The difference between Example 3 and Example 1 is:

[0038] In step (1), prepare PP6@AgNPs colloidal solution:

Abstract

The invention discloses a preparation method of a novel colorimetric supramolecular sensor for detecting amphetamine drugs. A novel colorimetric supramolecular sensor. The novel colorimetric supramolecular sensor constructed by the invention has the advantages of high sensitivity, rapidity, simplicity and time saving, and can realize rapid detection on site. It is expected to realize the visual on-site rapid identification and colorimetric detection of amphetamine drugs and to broaden the potential application of macrocyclic supramolecular receptors as molecular devices in the construction of supramolecular sensors.

Description

technical field [0001] The invention relates to the technical field of drug detection, in particular to a preparation method of a novel colorimetric supramolecular sensor for detecting amphetamine drugs. Background technique [0002] At present, countries around the world are facing the severe challenge of drug abuse. According to the 2013 World Drug Report published by the United Nations Office on Drugs and Crime, the drugs currently prevalent in the world mainly include opiates, amphetamine-type stimulants, and marijuana. Among them, the seizure, production and consumption of amphetamine-type stimulants are increasing year by year, and methamphetamine, namely methamphetamine, accounts for 71% of amphetamine-type stimulants. Cases of robbery, theft, violent injury, and driving accidents caused by drug use are on the rise, seriously endangering social security and public safety. Drug detection is an important technical means to expose and confirm drug trafficking and other...
