A method for producing an arrangement is provided. The arrangement includes a plurality of layers, whereby an organic layer is formed on a surface of a semiconductor substrate, under the influence of irradiated light, by applying a medium containing an organic substance to the surface of the semiconductor substrate, and deposition of the organic substance. A difference in potential is created between the semiconductor substrate and the medium during the deposition of the organic substance, by applying an electrical voltage. The invention also relates to a biosensor comprising an arrangement of a plurality of layers, and to a method for measuring properties of a test constituent using the biosensor. The arrangement of a plurality of layers comprises a semiconductor substrate layer and a layer which is arranged adjacent to the semiconductor substrate layer and contains a biologically active constituent. An interaction section is formed in active communication with the layer containing the biologically active constituent, and a test substance containing a test constituent for interacting with the biologically active constituent can be introduced into said section. Furthermore, said arrangement is provided with at least one connection electrode that is electroconductively connected to the interaction section, and another connection electrode that is electroconductively connected to the semiconductor substrate layer. The at least one connection electrode and the other connection electrode form connection means for coupling to an electric circuit such that an electrical measuring quantity can be obtained between the at least one connection electrode and the other connection electrode, over the arrangement of the plurality of layers and the interaction section, said measuring quantity being able to be modified as a result of the interaction of the test constituent with the biologically active constituent.
