  • Method for functionalizing a solid substrate, other than a substrate made of gold, via specific chemical compounds
    Patent number: 10002769
    Abstract: The invention relates to a method for functionalizing an electrically conductive substrate, which is not a substrate made of gold, via a layer of chemical compounds, said method comprising the following steps: a step in which the electrically conductive substrate is placed in contact with chemical compounds comprising at least a disulfide terminal group; a step in which the disulfide terminal group of said chemical compounds is electro-oxidized, causing said chemical compounds to form a layer at the surface of the electrically conductive substrate.
