The invention relates to a method for producing a detection system for
detecting different analytes in a sample, characterised by the following
steps: providing a planar or essentially planar substrate which has
sensors for chemically, optically or electrically detecting the analytes;
applying an already microstructured layer to the substrate or applying a
continuous layer to the substrate and microstructuring said layer, the
layer being applied in such a way in either case that the areas of the
substrate that are separated from each other are not covered by the layer,
the layer and substrate being sealingly interconnected at least around the
uncovered areas; bringing at least some of the uncovered areas into
contact with at least one liquid containing catcher molecules, in such a
way that said catcher molecules are able to adhere or bond to the surface
of the substrate and/or on the surface of the sensors; removing the
non-adhering constituents of the liquid and removing the microstructured
layer or parts thereof.
