Abstract: The present invention relates to a method for preventing the metallization of a support of at least one plastic part subjected to a metallization process, comprising the successive stages of oxidation of the surface of said part, of activation of the oxidized surface and of chemical and/or electrochemical deposition of metal on the activated surface, characterized in that it comprises a stage in which said support, before said oxidation stage, is brought into contact with an inhibiting solution comprising at least one specific metallization inhibitor. The invention also relates to a process for the selective metallization of a plastic part combined with a support, comprising bringing said part into contact with said inhibiting solution.

Abstract: A method for preventing, reducing and/or eliminating the fouling of a composite material is provided, the composite material comprising (1) a plurality of conductive or semiconductive nanotubes, which are aligned parallel to one another, and (2) a matrix arranged between the conductive or semiconductive nanotubes, the composite material in the form of an isoporous membrane with nanopores which correspond to the pores of the conductive or semiconductive nanotubes and optionally to the pores of the matrix arranged between the conductive or semiconductive nanotubes, the method comprising applying an electric field to the composite material, wherein the fouling is prevented, reduced and/or eliminated at the surface, at and in the pores of the composite material.

Abstract: An implantable material has at least one external surface grafted with a film including carboxylate and sulfonate functions wherein the film is simultaneously synthesized and grafted directly on the external surface by radical reaction of a source of carboxylate functions, the source being either polymerizable or chemisorbable and polymerizable and a source of sulfonate functions, the source being either polymerizable or chemisorbable and polymerizable. A process for simultaneously synthesizing and grafting a film directly onto at least one external surface of an implantable material, and the use of a grafted implantable material for the manufacture of an antiproliferative and/or antibacterial implantable medical device are also described.

Abstract: The present invention concerns a device comprising (i) a composite material comprising (1) a plurality of conductive or semiconductive nanotubes, and (2) a matrix arranged between these nanotubes and (ii) means allowing said composite material to be subjected to an electric field. The present invention also concerns the uses of said device in particular to defoul or to modify a composite material and to electroporate at least one cell.

Abstract: The present invention relates to a material comprising (i) nanotubes or nanowires aligned with each other in a vertical matrix and (ii) a matrix arranged between the nanotubes or the nanowires, at least one organic polymer being covalently grafted to at least two of said nanotubes or to at least two of said nanowires. The present invention also relates to a method for preparing such a material or to its uses.
