  • Patent number: 11802836
    Abstract: A process for detecting the sensitivity of one or more polymers and/or of one or more, mixtures of polymers to a compound, including the steps of exposing at least one lens-shaped micro-deposit, including the polymer(s) and/or the mixture(s) of polymers, to the compound, and detecting, by illuminating the surface of this micro-deposit, a change in the spatial distribution of the intensity of the light reflected or transmitted by this micro-deposit, linked to a variation in the dimensions and/or refractive index of this micro-deposit, under the effect of an interaction between the polymer(s) and/or the mixture(s) of polymers and the compound.
    Type: Grant
    Filed: June 1, 2018
    Date of Patent: October 31, 2023
    Assignees: Universite De Lille, Centre National De La Recherche Scientifique

  • Patent number: 11635372
    Abstract: A process for detecting the sensitivity of one or more polymers and/or of one or more mixtures of polymers to a compound, including the steps of exposing a plurality of individualized micro-deposits including the polymer(s) and/or the mixture(s) of polymers to the compound, and detecting, by interferometry, a variation in appearance of an assembly of micro-deposits exposed to the compound and/or a variation in the dimensions and/or refractive index of at least one of the micro-deposits exposed to the compound, linked to an interaction between the polymer(s) and/or the mixture(s) of polymers and the compound.

  • Publication number: 20120134880
    Abstract: The present invention relates to an apparatus for detecting one or more analytes, for example analytes selected from the group comprising nucleic acids, metabolites, peptides, proteins, hormones, pesticides, neurotransmitters, ions in blood, electrolytes, toxic gases, pH and biological warfare agents, the apparatus comprising an insulating substrate, at least one first electrode on the substrate at least one elongate nanostructure extending from and electrically connected to the or each said electrode and extending over the surface of the wafer away from the respective electrode, a passivating layer covering the or each electrode, but not all of said at least one elongate nanostructure, a well crossing the at least one elongate nanostructure extending from the or each electrode and forming a static reservoir for a liquid being investigated for the presence of at least one analyte, a reference electrode provided on said substrate within said well or insertable into said well and respective readout pads electri
