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.

Method for producing a device for electrochemical detection of molecules by way of redox cycling, device therefor and the use thereof

Transferring graphene pieces onto a substrate, by the following steps: a) selecting a substrate comprising a plurality of placeholders for the graphene pieces; b) disposing and aligning the substrate on a substrate holder in a chamber; c) selecting a transfer layer having openings as placeholders for the graphene pieces; d) disposing and aligning the transfer layer on the substrate holder over the substrate so that the openings of the transfer layer are aligned over the placeholders on the substrate; e) adding liquid to the chamber to above the transfer layer, and raising the transfer layer on the liquid column; f) introducing graphene pieces onto the liquid film in the openings of the transfer layer; and g) reducing the distance between the substrate and the graphene pieces until the graphene pieces are disposed on the placeholders of the substrate. A substrate and a device for carrying out the method.
