▎ 摘　　要

NOVELTY - The electrochemical biosensor (600) has an electrode substrate (602) configured for electrical measurements of a functionalized area (604) of a surface of the electrode substrate. The area is formed in a mixture (608) of molecular imprinting polymer (MIP), particles and one or more immobilizer materials. The MIP particles have imprints of a molecule sensed by the biosensor. The electrode substrate comprises a screen-printed carbon electrode and the mixture is provided as a thin film. The immobilizer material comprises chitosan, carbon nanodots, graphene, graphene oxide, or reduced graphene oxide. USE - Electrochemical biosensor e.g. salivary cortisol biosensor for use in cortisol detection and stress screening. Can also be used for monitoring customer wellness. ADVANTAGE - The electrochemical biosensor is highly selective, simple, fast and easy-to-operate, and facilitates the real-time monitoring of consumer wellness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of fabricating an electrochemical biosensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an electrochemical biosensor.
