Abstract

The invention provides a micro-fluidic-channel miniature assembly type biosensor structure which comprises a bracket and a flexible circuit board, wherein a working electrode and a counter electrode are arranged on the flexible circuit board; the bracket comprises a middle supporting seat, the middle supporting seat is provided with a micro-fluidic channel, and the micro-fluidic channel penetratesthrough the high direction of the middle supporting seat; the flexible circuit board is bent, the working electrode and the counter electrode are located on the two opposite surfaces in the bent flexible circuit board respectively, and the working electrode and the counter electrode extend into the micro-fluidic channel from the two sides of the high direction of the micro-fluidic channel; and the top surfaces of the working electrode and the counter electrode are arranged oppositely. The working electrode (WE) and the counter electrode (CE) / a reference electrode (RE) are separated, are connected by a flexible bending structure and can be subjected to batch processing separately; meanwhile, when being coated with an enzyme and immobilized with the enzyme, the WE is far away from other electrodes, so that refining operation can be conveniently carried out; the production efficiency and the design precision are improved; and the micro-fluidic channel is ingeniously arranged in the middle of the bracket, so that the structure is compact and flow of a fluid is convenient.

Description

technical field [0001] The invention relates to the technical field of biochemical parameter acquisition, in particular to a micro-channel micro-assembled biosensor structure. Background technique [0002] Due to the requirements of the working principle, the working electrode and the counter electrode of the biosensor need to be arranged relatively close to each other. In the prior art, in the production process, due to the influence of the material difference between the working electrode and the counter electrode, the process is complicated and the manufacturing difficulty is high; the manufacturing process requires a large distance between the working electrode and the counter electrode; the manufacturing process and structure The contradiction between the principles limits the development of biosensors. Contents of the invention [0003] In view of the above, the present invention provides a micro-channel micro-assembled biosensor structure, the distance between the ...
