This invention concerns a versatile and simple one-pot method to prepare nanomaterials, and in particular nanoparticles, grafted with an ultra-thin layer of calixarenes by placing at 5 least one oxidized metal with at least one calix[n]arene diazonium salt in the presence of a reducing agent in a solvent, and heating the traction mixture to obtain a metal-based nanomaterial coated with calix[n]arenes. The invention further concerns the coupling of organic molecules or biomolecules to the calixarene-grafted nanomaterials in order to further functionalize the surface of the particles. The metal-based nanomaterial coated with 10 calix[n]arenes can for example be used in immunoassays.
