Abstract
The invention provides a blood glucose sensor planted in live fish eye ball sclera interstitial fluid and a production method of the blood glucose sensor and aims to solve the problem that a blood glucose sensor planted into a fish body is difficult to measure the blood glucose concentration in the live fish body stably and in real time in the prior art. The blood glucose sensor comprises sensor base material and a wireless transmitting device electrically connected with the sensor base material. The sensor base material comprises a working electrode and a reference electrode. One end of the working electrode is provided with a sensing cavity. An insulating layer coats a part from the other end of the working electrode to the sensing cavity. The reference electrode wraps the outer surface of the insulating layer. The reference electrode comprises a copper wire on the outer surface of the insulating layer and a silver / silver chloride paste layer covering the copper wire. A perfluorosulfonate polymer membrane covers the outer surface of the sensing cavity of the working electrode, and a glucose oxidase layer covers the outer surface of the perfluorosulfonate polymer membrane. The blood glucose sensor planted in live fish eye ball sclera interstitial fluid is high in blood glucose detection accuracy and portability and good in stability.
Description
technical field [0001] The invention relates to a bioelectrochemical detection technology, in particular to a blood sugar sensor planted in the interscleral interstitial fluid of living fish eyes and a preparation method thereof. Background technique [0002] Fresh fish is favored by consumers because of its delicious taste, high nutritional value, and rich in high-quality protein, vitamins and trace elements. The blood glucose level of live fish is an important indicator reflecting the stress level of live fish during transportation. Real-time wireless monitoring to obtain the blood sugar level of live fish is the reference basis for continuous improvement of fresh fish transportation technology and equipment; at the same time, with the help of biosensing technology and wireless communication technology, minimally invasive implantation in fish body, real-time monitoring of live fish during transportation Different stress blood sugar levels at each stage of the process is a...
