Method and arrangement for electrically contacting an object with a membrane-electrode

The invention relates inter alia to a method for electrically contacting a membrane-enveloped object (30) having an electrode (10, 100). According to the invention it is provided that at least one electrode (100) having a conductive support (110) is used for contacting, on which a plurality of nano-wires (120) and have a spacing on the adjacent nanoneedles to each other which is smaller than the size of the is the object, and that the object is brought into contact with the nanoneedles.
