Patents by Inventor René Pellaux

René Pellaux 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).

  • Patent number: 8546145
    Abstract: The invention relates to a method of fast identification and isolation of cells featuring a desired phenotype. The phenotype is coupled to the amount of gas-liberating enzymes or increased growth. The cells are encapsulated into microcapsules allowing exchange of solvents through the microcapsule wall, but retaining some or all of the gas formed by gas-liberating enzymes on contact with corresponding substrates. Microcapsules containing increased amounts of gas-liberating enzymes are starting to float and can be separated. The cells are then isolated from the microcapsules according to standard procedures.
    Type: Grant
    Filed: May 27, 2011
    Date of Patent: October 1, 2013
    Assignee: ETH Zurich
    Inventors: René Pellaux, Marcel Walser, Andreas Jörg Meyer, Martin Held, Sven Panke

  • Publication number: 20050013788
    Abstract: The invention relates to sorptive composite materials comprising a sorbent entrapped in a cross-linked acrylic polymer. These composites can be tailored for extraction and feeding of compounds from/to liquid phases or multiphase systems such as cell suspensions. Key features of the sorptive composite materials arc stability (chemical, mechanical, biological and thermal), selectivity (physical and chemical), biocompatibility, and a characteristic upon which the sorptive composite materials can be separated from liquid or multi-phase systems. The invention also relates to techniques for the preparation of such sorptive composite materials as well as applications thereof.
