The chemical species are fixed to the surface of the three-dimensional nanostructured sites by covalent bonds in which the three-dimensional nanostructured sites are equipped with a porous layer. The surface of the porous layer is equipped with chemical coupling functions. The intermediate layer is made of dielectric or insulation material. The three-dimensional nanostructured sites are separated from each other in which the sites are porous grains in a form of hemispherical/spherical. The porous grains have a diameter of 2-150 nm.
