Title:
ELECTROCHEMICAL SENSOR AND PREPARATION METHOD THEREFOR AND USE THEREOF IN DETECTING GINSENOSIDE RG3
Document Type and Number:
WIPO Patent Application WO/2023/015824
Kind Code:
A1
Abstract:
An electrochemical sensor and a preparation method therefor and the use thereof in detecting ginsenoside Rg3. A electrochemical sensor comprises an electrode, a composite material attached to the surface of the electrode and a molecularly imprinted polymer, wherein the composite material is a composite of multi-walled carbon nanotubes and titanium carbide, and the template of the molecularly imprinted polymer is ginsenoside Rg3. The preparation method therefor comprises adding multi-walled carbon nanotubes and titanium carbide to a solvent containing diethylene glycol diacrylate phthalate for compounding, so as to obtain a composite material of multi-walled carbon nanotubes, titanium carbide and diethylene glycol diacrylate phthalate, and modifying the surface of the electrode by using the composite material to form a modified electrode; using o-phenylenediamine as a functional monomer and ginsenoside Rg3 as a template molecule, and performing electropolymerization on the surface of the modified electrode to form the molecularly imprinted polymer, i.e. to obtain the electrochemical sensor. The electrochemical sensor is used to detect ginsenoside Rg3, which has the advantages of a low cost, a fast response and a high sensitivity.
