Claim Text:
1. A process for the deposition of nanoparticles made of a conducting or semiconducting or insulating material on predetermined regions Z made of a conducting or semiconducting material of a substrate S, wherein the process comprises the following stages: a) creating, around the regions Z, regions I made of an insulating material, when these regions I are not already present, b) depositing, by electrografting, on the conducting or semiconducting material constituting the regions Z, a polymer P prepared from diazonium salt or from ammonium salt or from sulfonium salt or from iodonium salt or from alkyl halides or from vinyl monomers or from a mixture of these, c) coating the nanoparticles with a coating material comprising a bifunctional molecule capable of creating a bond with the nanoparticles and a bond with the polymer P, d) suspending the coated nanoparticles obtained in stage c) in a solvent e) immersing the substrate S obtained in stage b) in the suspension obtained in stage d), and f) removing the polymer P.
