Abstract
The invention relates to a method for producing a device for the electrochemical detection of molecules by way of redox cycling, to a device therefor, and to the use thereof. A porous dielectric layer is present between two electrode layers, which is able to receive redox-active molecules and may be biofunctionalized. The individual layers are preferably applied by way of an ink jet printing method.
