Matthieu Jean Michel RUEEGG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Devices and systems for optically determining a concentration of an analyte in a living subject using hydrogel-based, fluorescent microneedles and methods of manufacture thereof
    Patent number: 10631766
    Abstract: At least one microneedle comprises a hydrogel material that includes a substance that fluoresces when the substance interacts with an analyte. A magnitude of the fluorescence varies as a function of the concentration of the analyte. During use, the hydrogel material is illuminated with illumination light in a first wavelength range while the hydrogel material interfaces with the dermal interstitial fluid layer of a subject, and a photosensor generates an output that corresponds to an amount of light received in a second wavelength range.
    Type: Grant
    Filed: March 4, 2016
    Date of Patent: April 28, 2020
    Assignee: The Trustees of Columbia University in the City of New York
