Electrochemical Biosensor, Method For Producing The Same, And Method For Manufacturing Electrode Layer

Abstract

An electrochemical biosensor includes a substrate, a plurality of layered active metal parts, a plurality of layered electrodes, a reaction confinement layer, an electrochemical reactive layer and a cover piece. The substrate is formed with through holes each of which is defined by an interior wall surface and penetrates top and bottom surfaces. Each of the layered active metal parts is formed at least upon a respective one of the interior wall surfaces. The layered electrodes are formed on the layered active metal parts. The reaction confinement layer confines a reactor space over a region where the through holes are formed. The electrochemical reactive layer is disposed in the reactor space and is electrically coupled to the layered electrodes.

Description

technical field [0001] The invention relates to a sensory test piece and a manufacturing method thereof, in particular to an electrochemical sensory test piece which is easy to process and can reduce the cost of metal electrode raw materials and a manufacturing method thereof. Background technique [0002] refer to figure 1 , is an existing electrochemical test strip 8, which is suitable for testing the content of an analyte in a fluid to be measured, such as the blood sugar content in blood or the concentration of heavy metals in sewage, etc. The electrochemical test strip 8 includes an insulating substrate 81 . A metal conductive layer 82 printed on the insulating substrate 81 , a corresponding insulating layer 83 covering the insulating substrate 81 , a reagent reaction layer 84 corresponding to the metal conductive layer 82 , and a cover plate 85 . Although the electrochemical test strip 8 can achieve the purpose of detecting the content of the analyte, since the metal ...

AI Technical Summary

Problems solved by technology

Although the electrochemical test strip 9 can also achieve the purpose of detecting the content of the analyte, and compared with the above-mentioned electrochemical test strip 8, the consumption of metal electrode raw materials during manufacture is less, but because the electrodes 92 and the insulating substrate 91 are made separately Molding, then installation and combination, the production process is relatively cumbersome, and the size of the electrode 92 and the corresponding through hole 912 must be accurate enough to achieve a good degree of bonding
