A BIOSENSOR FOR ELECTROCHEMICAL ANALYSIS OF A LIQUID SAMPLE AND A METHOD FOR ASSAYING AN ANALYTE OR AN ENZYME IN A LIQUID SAMPLE.

摘要

The present invention discloses a biosensor for electrochemical analysis of a liquid sample comprising : an insulating base plate ; an electrode system on said insulating base plate, wherein said electrode system comprises a working electrode (silver paste DE and carbon paste EF) and a counter electrode (silver paste AB and carbon paste BC); a reaction area (HI) as part of said electrode system, comprising an en2yme that catalyzes a reaction involving an analyte to be analyzed or a substrate that is involved in a reaction catalyzed by an enzyme to be analyzed ; and a sample application and reaction chamber which facilitates the speed and uniformity of sample application. Method for assaying analytes or enzymes using the biosensor is also disclosed.
