Flexible glucose electrochemical sensor

The divisional application discloses a flexible glucose electrochemical sensor, belonging to the technical field of electrochemical sensors. A flexible electrode substrate is polydimethylsiloxane (PDMS), and a dendritic structure nano-silver conducting layer is arranged on the PDMS substrate. The preparation method comprises the steps of carrying out self-assembly of indium tin oxide (ITO) glass,carrying out electrochemical deposition of a dendritic structure nano-silver film layer on the ITO glass, putting the ITO glass with the nano-silver conducting layer into a PDMS solution for curing, and then removing the PDMS film from the ITO glass to obtain the flexible glucose electrochemical sensor based on a dendritic nano-silver structure. The flexible glucose electrochemical sensor providedby the invention has a good response to glucose, is simple in preparation method and is easy to mass production, thus being expected to be widely applied to industrial and agricultural production aswell as life science resear
