Abstract
Provided in the present invention are a flexible electrochemical electrode, a subcutaneous continuous glucose monitoring sensor equipped with the electrochemical electrode, and a preparation method thereof. The electrode directly uses gold layers on both sides of a chemically plated film, respectively as a working electrode and a reference-counter electrode, so as to form an electrochemical two-electrode system. Petaloid platinum nanoparticles are electrodeposited on a surface of the configured working electrode as a catalytic layer; a carbon nanotube/Nafion mesh layer functions as an anti-interference layer, and is formed thereon with an enzyme biochemical sensitive layer by means of electrostatic adsorption, after crosslinking and curing in glutaraldehyde, polyurethane mass transfer is coated to limit a protection layer, so as to prepare a flexible continuous glucose monitoring sensor. The sensor does not require photolithography, screen printing or other technologies to construct an electrochemical electrode system. The present invention effectively simplifies the processing technology, can easily achieve large-scale production and reduce production costs; and meanwhile, the pre…
