The invention relates to a method of detecting macromolecular biopolymers by means of an electrode arrangement that comprises a first and a second electrode. The inventive method is characterized by carrying out a first electrical measurement on the electrodes. In a further step, a solution to be examined, which may contain the macromolecular biopolymers to be detected, is contacted with the electrode arrangement. In another step, the macromolecular biopolymers to be detected that are contained it the solution to be examined are bound to the scavenger molecules on the first and on the second electrode and the electrode arrangement is contacted with a reagent to increase conductivity of the macromolecular biopolymers, said reagent binding to the macromolecular biopolymers and bestowing them with electroconductivity. A second electrical measurement is carried out on the electrodes and the macromolecular biopolymers are detected on the basis of the comparison of the results of the two electrical measurements on the electrodes. |
