Title:
METHOD FOR PREPARING SCREEN-PRINTED BIOELECTROCHEMICAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/197410
Kind Code:
A1
Abstract:
A method for preparing a screen-printed bioelectrochemical sensor. A conductive polymer, i.e., polyaniline, is deposited on the surface of a screen-printed carbon electrode by means of electropolymerization, wherein the conductive polymer has a strong adsorption property to be used for immobilizing the glucose oxidase so as to increase the long-term stability of the glucose oxidase on the carbon electrode; in addition, poly(ethylene glycol) glycidyl ether is used to cross-link a polymer, i.e., ferrocene and the glucose oxidase so as to further strengthen the immobilization of the glucose oxidase, and a hydrogel outer membrane having a cross-linking effect is added to further increase the stability of the product electrode and maintain good linearity.
