| 摘要 |
The invention relates to a biosensor for the determination of substances in bodily fluids, in particular, in blood, comprising a two-piece support plate, whereby the one piece of the support plate represents an upper piece and the other piece represents a lower piece, with an intermediate layer lying between the upper and lower piece in which an aperture is formed. The upper piece, lower piece and aperture form a capillary channel, running from a cover opening formed at the edge of the biosensor to an air hole formed in the upper piece or lower piece. Electrodes are provided, which together with an enzyme-containing substance permit an electrochemical measurement of substances found in body fluids. The upper piece and lower piece each support at least one electrode in the region of the capillary channel, which oppose each other in pairs and are arranged such that both electrode pairs form measuring regions lying within the capillary channel, whereby at least one of the electrodes of each electrode pair is treated with an enzyme-containing substance.
