Problems solved by technology

[0003] At present, the electrode materials of enzyme-free electrochemical glucose sensors have the defect that the process of detecting glucose is easily affected by other interfering substances (such as chloride ions, uric acid), thus affecting the accuracy of the detection results
Moreover, the linear range of the existing sensors for enzyme-free glucose detection is relatively narrow, which is far lower than the normal blood sugar concentration (fasting) range (4.4-6.6 mM) of the human body. The smaller linear range makes its application in diabetes detection subject to very restrictive

Abstract

The invention discloses nickel metal organic framework nanomaterials. The preparation steps are as follows: mixing an ethylene glycol solution of a divalent nickel salt and a dimethylformamide solution of terephthalic acid, stirring evenly, and heating the The hydrothermal reaction is carried out to obtain the precipitate produced by the reaction; the precipitate is washed with dimethylformamide and ethanol, and then dried to obtain the nickel metal organic framework nanomaterial. The sensor electrode prepared by the invention has a wide detection range for glucose, can detect 0.5 μM-8.062 mM glucose, has high detection sensitivity, and has good anti-interference performance for ascorbic acid, uric acid, dopamine and sodium chloride.

Description

technical field [0001] The invention belongs to the technical field of preparation of an enzyme-free glucose sensor, and in particular relates to a nickel metal organic framework nanomaterial and an application thereof. Background technique [0002] Glucose is the main characteristic compound of life process, and its analysis and detection are of great significance to human health and the diagnosis, treatment and control of diseases. Therefore, the research of glucose sensor has always been a hotspot in the research of chemical and biological sensors. Among them, the glucose electrochemical sensor is the earliest biosensor developed. Glucose electrochemical sensors can be divided into enzyme-based glucose electrochemical sensors and enzyme-free glucose electrochemical sensors according to whether enzymes are used to construct biosensors. Enzyme-based glucose electrochemical sensors use enzymes and thus have the characteristics of high specificity and fast response. However...
