According to a method for immobilizing macromolecules or organic biopolymers, in particular enzymes, antibodies, antigens, DNA / RNA and microorganisms, the macromolecules or biopolymers to be immobilized are mixed with an aqueous polymer dispersion which is free of solvent and this mixture is applied to a substrate. in the form of a film which is then carefully dried. The cohesive polymer film can in particular be applied to the measurement electrode of the transducer of a biosensor. |
