The invention discloses an electrochemical sensor for monitoring the glucose content of fish in real time and application of the electrochemical sensor, and belongs to the field of electrochemistry. The sensor comprises a three-electrode system consisting of a working electrode, a reference electrode and a counter electrode, the working electrode takes a platinum-iridium alloy wire as a substrate, the surface of the working electrode is coated with a composite membrane consisting of a carbon nanotube and naphthol, and glucose oxidase is fixed on the composite membrane through physical adsorption and chemical crosslinking. The glucose detection sensitivity of the sensor is higher than 0.215 nA / mmol.L <-1 >, the response speed is high, the stability is good, the anti-interference capability is high, and the sensor has very high correlation with the detection result of a glucometer. According to the invention, real-time in-vivo monitoring of the fish glucose content is realized, and powerful technical support is provided for green and sustainable development of aquaculture.

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.

The embodiment of the invention discloses a fusion data secure transmission method applied to glucometer equipment and an intelligent glucometer, and the method comprises the steps: reading user identity information through a multimode identity recognition module, and obtaining an eID signature online when the user identity information is recognized as an eID carrier; blood glucose data are collected, and the code ID of the blood glucose test paper is automatically read to call accurate calibration parameters; the main control chip binds the eID signature, the calibrated blood glucose data and a timestamp to generate a trusted data chain with judicial evidence storage efficacy; and after being subjected to hardware-level encryption storage, the data are transmitted to a server through a national secret encryption channel, and continuous transmission after network disconnection is supported. The system integrates an identity card, a social security card and a multimode identity recognition module of an eID radio frequency unit; and the blood glucose detection module is provided with a test paper ID automatic identification circuit. According to the invention, the data credibility and security of the whole process from the detection source to the cloud management are realized, and the technical problems of easy error of identity binding, data source error, fragile transmission security and difficult cross-network identity tracing are solved.
