Problems solved by technology
Its disadvantages are poor accuracy and low sensitivity, and it can only be used for semi-quantitative detection of urine sugar
Although the accuracy of the urine analyzer has been improved compared with the detection test paper, it can only be used for semi-quantitative detection and cannot achieve accurate quantification.
In addition, regardless of colorimetric reflectance method or electrochemical biosensor method, various impurities in urine will seriously interfere with the detection of urine sugar.

Embodiment Construction
[0022] The present invention will be further explained below in conjunction with specific embodiments.
[0023] A detection method for detecting blood sugar, comprising the following steps:
[0024] S1. Sampling: Cut aluminum foil with a thickness of 0.02cm into 2cm×2cm aluminum sheets, polish with sandpaper to remove surface pollutants, clean with acetone to remove surface grease, clean with ethanol to remove organic matter, and then clean with an ultrasonic cleaner dry;
[0025] S2, remove the oxide layer: use 1.25mol / L sodium hydroxide solution to clean the aluminum sheet for 2 minutes, then clean it with an ultrasonic cleaner, and place the cleaned aluminum sheet in air to dry;
[0026] S3. Etching: immerse the aluminum sheet in 4mol / L hydrochloric acid and etch for 2 minutes. After the etching is completed, clean it with an ultrasonic cleaner, and put the cleaned aluminum sheet in an oven and dry it for 30 minutes at 80°C;
[0027] S4. Soaking and drying: immerse the al...

Abstract
The invention relates to the technical field of blood glucose detection, in particular to a detection method for detecting blood glucose. The method comprises the following steps: S1, taking an aluminum sheet and removing pollutants, grease and organic matters on the surface of the aluminum sheet; S2, removing an oxide layer on the surface of the aluminum sheet; S3, etching the aluminum sheet, andobserving the microstructure of the prepared aluminum surface by using a scanning electron microscope; S4, soaking the aluminum sheet in an ethanol solution of tridecafluorooctyltriethoxysilane hydrolyzed in advance, and drying the aluminum sheet; S5, dripping water drops on the surface of the aluminum sheet, and measuring a contact angle to be more than 150 degrees by using a contact angle measuring instrument; S6, reversely solving the sugar degree of the serum according to a linear relationship between the sugar content of the serum and the contact angle, and recording the sugar degree. Bydetecting the contact angle of the serum and utilizing the linear relationship between the sugar content of the serum and the contact angle, the sugar degree of the blood is reversely solved, and compared with the prior art, the blood glucose detection convenience is greatly improved, and the popularization and the use are facilitated.
Description
technical field [0001] The invention relates to the technical field of blood sugar detection, in particular to a superhydrophobic aluminum foil for detecting blood sugar and a detection method thereof. Background technique [0002] Diabetes is a high-incidence disease. It is often difficult to detect in the early stage or without typical symptoms. It is a chronic disease process. Patients often develop complications (such as cardiovascular and cerebrovascular diseases, vision loss, hyperviscosity, etc.) in 15-20 years. It was only later that I realized that I had suffered from diabetes for many years. In clinical treatment, in order to control the complications of diabetes, it is necessary to regularly detect the glucose concentration in human blood. This is not only a must for type 1 diabetics but also for type 2 diabetics. [0003] Since the blood glucose tolerance test, blood glucose test, and fingertip test all require periodic dynamic testing of the regulation level o...
