1. Biosensor for analyzing biological fluids, said biosensor comprising at least the following layers:
- a functional layer A1 which constitutes a base layer of the biosensor and is provided with electrical interconnects and at least partially with an analytical detection reagent,a functional layer A3 anda double-sided pressure-sensitive adhesive tape A2 which joins the functional layers A1 and A3 to one another and in which a measuring channel is provided having a lid formed by the functional layer A3 and a base formed by the functional layer A1,the functional layer A3 having at least one hydrophilic and at least one hydrophobic region, the hydrophobic and hydrophilic regions of the functional layer A3 being disposed such that they at least partially form an inside of the wall of the measuring channel formed by the functional layer A2, andone hydrophilic region of the functional layer A3 ends at a front edge of the measuring channel, from which the biological fluid is supplied to the medical biosensor.

Abstract
Biosensor for analyzing biological fluids having:
- a functional base layer A1 provided with electrical interconnects and at least partially with an analytical detection reagent,
- a functional layer A3 and
- a double-sided pressure-sensitive adhesive tape A2 which joins the functional layers A1 and A3 and forms a measuring channel whose lid is formed by functional layer A3 and whose base is formed by functional layer A1,
the functional layer A3 having at least one hydrophilic and at least one hydrophobic region, the hydrophobic and hydrophilic regions being disposed such that they at least partially form an inside of the wall of the measuring channel formed by functional layer A2, and one hydrophilic region of the functional layer A3 ends flush with a front edge of the measuring channel, from which the biological fluid is supplied.
