    摘要: Device for capturing a target molecule for the purpose of detecting it and/or assaying it, including a solid support on which is immobilized a ligand, the ligand being provided in the form of a conjugate resulting from the covalent coupling of a polymer with a plurality of molecules of the ligand. The polymer is an N-vinylpyrrolidone copolymer, and the conjugate is immobilized on the solid support by adsorption. When the ligand is capable of forming a complex with the target, the device is specific for a given target. When the device comprises, in addition, a bifunctional reagent capable of forming a complex, on the one hand, with the ligand and, on the other hand, with the target, the support on which the ligand is immobilized constitutes a universal capturing system.
