Abstract
The invention relates to a self-driven all-solid-state glucose biosensor and a preparation method thereof. According to the self-driven all-solid-state glucose biosensor and the preparation method thereof, self-driven glucose concentration detection is realized, glucose concentration can be detected under the illumination and non-illumination conditions, the linear detection range reaches 2-40 mM, and glucose concentration detection requirements of a normal human body (with the linear detection range of 3.61-6.11 mM) and a diabetic patient; light conversion, light storage and biosensing are integrated to one device, a new field is developed for miniaturization and portability of the biosensor, and the biosensor is assembled by adopting a Sn<2+> doped SnO2 nanosheet array as a photoresponse electrode and adopting a rhombic NiCo2O4 nanorod array as an electrochemical energy storageelectrode through a Celgard 2400 diaphragm and a PVA / KOH solidelectrolyte.
Description
(1) Technical field [0001] The invention relates to a SnO-based 2 / NiCo 2 o 4 Self-driven all-solid-state glucose biosensor and its preparation method. (2) Background technology [0002] Since human society entered modern civilization, with the improvement of people's material living standards, "diseases of wealth" such as diabetes have spread widely all over the world, and about 400 million people suffer from diabetes every year. Therefore, the daily monitoring of diabetes has become an urgent problem to be solved. In order to facilitate daily use, it is necessary to make its core component, the glucose sensor, small and portable. However, many current glucose sensors usually require an external power supply to provide energy, which virtually increases the size of the sensor. Self-driven biosensors open up a new direction for the miniaturization of sensors. [0003] As an inexhaustible energy source on the earth, solar energy can provide a good energy source for biose...
