  • Biocompatible electrochemical supercapacitor
    Patent number: 9941522
    Abstract: A supercapacitor to be submerged in a medium containing a biological material and an oxidant, wherein the anode comprises a first enzyme that can catalyse the oxidation of the biological material and the cathode comprises a second enzyme that can catalyse the reduction of the oxidant, and wherein each of the anode and cathode electrodes consists of a solid agglomerate of a conductive material mixed with the first or the second enzyme, said agglomerate having a specific surface that is larger than or equal to 20 m2/g and an average pore size varying between 0.7 nm and 10 pm.
    Type: Grant
    Filed: March 4, 2014
    Date of Patent: April 10, 2018
    Assignee: Universite Joseph Fourier
    Inventors: Serge Cosnier, Michael Holzinger, Alan Le Goff, Charles Agnes
  • Functionalization of sphybridized carbon, silicon and/or germanium surfaces
    Patent number: 9287517
    Abstract: The invention concerns a method for preparing a grafted material comprising the following steps: a) providing a material which, on its surface, comprises sp3 hybridized carbon, silicon and/or germanium atoms carrying at least one hydrogen atom, and b) contacting in a solvent the material such as provided at step a) with a compound (C) carrying at least one amine function in the unprotonated state, whereby the said compound (C) is grafted onto the said material.
    Type: Grant
