A measuring electrode (27) and an adjacent electrode (28) are embedded in an insulating substrate (26). The exposed surface of the electrode system is coated with a porous substance (29) carrying an oxidation reductase (30) and, if needed, an electron acceptor (31) in a dry state, to form a biosensor. A predetermined voltage is applied between the electrodes (27, 28) of the biosensor, and a matrix-containing sample is dropped on the porous substance (29). A current proportional to the substrate concentration flows, so it is possible to quantitatively determine the matrix concentration of various biological samples highly accurately, rapidly and easily.
