  • Patent number: 8394460
    Abstract: A process for mask-free localized grafting of organic molecules capable of being electrically activated, onto a composite surface comprising conductive and/or semiconductive portions, by placing said organic molecules in contact with said composite surface, in which said grafting is performed electrochemically in a single step on chosen, defined areas of said conductive and/or semiconductive portions, said areas being brought to a potential higher than or equal to a threshold electrical potential determined relative to a reference electrode, said threshold electrical potential being the potential above which grafting of said organic molecules takes place.

  • Patent number: 8263488
    Abstract: The invention relates to the deposition or attachment of materials to surfaces. It relates to a process for coating a surface with a first material and a second material, comprising the following steps: placing the first material on the said surface, inserting into the first material placed on the said surface precursor molecules of the second material, converting the said precursor molecules of the second material inserted into the first material into the said second material such that this second material becomes formed on the said surface to be coated and within the said first material placed on the said surface. The object of the process of the invention is to allow the deposition of materials of any type onto surfaces of any type.

  • Publication number: 20100279900
    Abstract: The present invention provides a method for encapsulating biocompatible polymers. The method comprises using a solid support comprising at least one electrically conducting and/or semiconducting region containing a reducible oxide on its surface, wherein at least one zone of this surface is functionalized with an electrografted organic film obtained from electroactive organic precursors each comprising at least one functional group of interest, and wherein the number of functional groups of interest accessible for the formation of a covalent, ionic or hydrogen bond with a complementary group within said film represents at least 90% of the total number of functional organic groups of interest, and wherein the density of the accessible functional groups of interest is between 104/?m2 and 1010/?m2. The method further comprises attaching molecules of interest or objects bearing a complementary function to the solid support.

  • Publication number: 20040081900
    Abstract: The invention concerns a mask-free localised grafting of organic molecules capable of being electrically activated, on a composite surface comprising conductive and/or semiconductive portions, by contacting said organic molecules with said composite surface, whereby the grafting is carried out electrochemically in one single step on specific selected zones of said conductive and/or semiconductive portions, said zones being brought to a potential not less than an electric potential threshold determined relative to a reference electrode, said electric potential threshold being the potential beyond which the grafting of said organic molecules occurs.
