Problems solved by technology

At this time, graphene nanosheets tend to re-stack and graphitize, resulting in a decrease in their electron conduction efficiency; and the dispersion in the solution drops sharply, forming a heterogeneous solution or film, which seriously hinders its use in actual research and commercial products. The application of graphene is one of the problems that need to be solved urgently in the field of graphene research

Embodiment 1

[0075] A bilirubin responsive electrode prepared by the following method:

[0076] (1) Preparation Solution: Method: Cool the diethyl ether solution to -78°C, then add TTF powder and lithium diisopropylamide according to the proportion of the reaction chemical formula, and cool it fully; then pass in carbon dioxide gas for 1 hour, continue stirring at low temperature for 12 hours, wash, Filter to obtain carboxylated TTF-COOH powder material;

[0077] (2) Preparation of gold nanoparticle sol by liquid-phase synthesis method: All experimental devices were immersed in aqua regia solution for 12 hours, washed with ultrapure water for 3 times, and placed for use. 2 mL of 1.0% HAuCl 4 Solution and 5mL of 1% sodium citrate solution were mixed and stirred, and diluted with 200mL of ultrapure water into a 400ml beaker; after uniform stirring, the color of the solution changed from blue to wine red; after that, the solution was continued to be heated After 10 minutes, remove the hea...

Abstract

The invention provides a bilirubin response electrode. The electrode includes an electrode body. A graphene composite material, a biocompatible material and a bilirubin specific-recognition enzyme areadsorbed at the electrode. The graphene composite material includes a tetrathiafulvalene derivative and graphene dispersed in the tetrathiafulvalene derivative. The tetrathiafulvalene derivative hasa structure of a formula (I). The designed bilirubin response electrode of the invention utilizes changes of electrical signals after bilirubin oxidase and bilirubin binding reaction to obtain bilirubin content data, and response time is short.

Description

technical field [0001] The invention belongs to the technical field of electrochemical sensors, and in particular relates to a bilirubin responsive electrode, a preparation method thereof, a bilirubin detector comprising the same and a use method thereof. Background technique [0002] Bilirubin is an important basis for clinically judging jaundice and an important indicator of liver function. It is very important to efficiently, quickly and accurately determine its content in human blood. At present, the methods for measuring serum bilirubin mainly include diazonium reagent method, bilirubin oxidase method, vanadate oxidation method, etc., all of which are based on the chemical reaction phenomenon of bilirubin and other reagents and the change of absorbance to determine its content in detail. Measured. [0003] CN 106896102A discloses a total bilirubin detection reagent, the composition of which is: preservative 6-8wt%; Tris-HCl buffer solution 160-180mmol / L; sodium lauryl ...
