Abstract: Apparatus for galvanically growing a plurality of nanowires on a substrate, comprising a substrate holder and a housing, in which a chamber, a control unit and a storage tank for an electrolyte are arranged, the apparatus being designed to grow the plurality of nanowires from the electrolyte onto the substrate when the substrate holder with the substrate has been inserted into the chamber.

Abstract: Method for galvanically growing a plurality of nanowires on a substrate, comprising a) placing a foil onto the surface, the foil having a plurality of passing-through pores, in which the nanowires can be grown from an electrolyte, b) placing an elastic element that is permeable to the electrolyte onto the foil, the electrolyte being brought into contact with the foil by way of the elastic element, c) for a first growing time period, galvanically growing the plurality of nanowires, d) removing the elastic element, and e) for a second growing time period, continuing the galvanic growing of the plurality of nanowires.

Abstract: Apparatus for galvanically growing a plurality of nanowires on a substrate, comprising a substrate holder and a receptacle for the substrate holder, the apparatus being designed to grow the plurality of nanowires on the substrate when the substrate holder with the substrate has been received in the receptacle, the substrate holder having electronics which are designed to influence the growing of the nanowires.

Abstract: A method for producing a detection system for biomolecules in a medium involves providing a first detector section having a first channel region and a second detector section having a second channel region. A membrane having at least one pore is provided and the first detector section and the second detector section are arranged on opposite sides of the membrane, such that at least part of the first channel region and the second channel region are separated by the membrane and the first channel region and the second channel region are connected to each another to form a channel system, in order to form a flow path for the medium through the at least one pore of the membrane. Along the flow path, through the membrane, bioreceptors are bound and/or coupled to the membrane in order to determine a concentration of the biomolecules in the medium by means of a measurement of the flow along the flow path.
