| 1. A method for attaching macro-objects to an electrically conducting or semiconducting surface by electrografting, comprising:
a) preparing an electrolyte solution comprising, in dissolved, particulate or emulsified form, at least one macro-object consisting
of a macrostructural portion functionalized with at least one electroactive group and capable of resulting in the electro
grafting of said macro-object to said surface, said electrolyte solution having a proton content of greater than or equal
to 50 ppm, the said protons being provided by the solvents which make up said solution and/or by the macro-objects used in
the course of the electrografting method and being present in the electrolyte solution; then
b) electrolyzing said solution in an electrolysis cell using the conducting or semiconducting surface to be coated as working
electrode and at least one counterelectrode, so as to result, by electroreduction or electrooxidation of said solution, in
a grafted coating of said macro-object or of its condensation products on said surface.
