A glucose meter is a medical device for determining the approximate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart. It is a key element of home blood glucose monitoring (HBGM) by people with diabetes mellitus or hypoglycemia. A small drop of blood, obtained by pricking the skin with a lancet, is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level. The meter then displays the level in units of mg/dl or mmol/l.

A method for preparing an MOF-based glucose detection system, wherein a Zeolitic Imidazolate Framework (ZIF) is used as a metal-organic framework, and glucose oxidase (GOx) is loaded in the zeolitic imidazolate framework. The preparation method comprises the following steps: S1: adding water to a reaction flask in advance, and then sequentially adding a metal ion, an enzyme and an organic ligand in a molar ratio of 100-1500:1-10:1-150, and 0.1-0.5% (by weight) of ammonia water to the reaction flask, S2: mixing and reacting same at room temperature for more than 6 hours, and S3: after centrifugation by means of a centrifuge, removing the supernatant to obtain a solid precipitate of the Gox-MOF material loaded with glucose oxidase. A sensor for detecting trace glucose concentration in saliva, and an oral glucose meter comprising the sensor.
