  • Immobilization of biomolecules on a fluorocarbon surface with a poly(fluoroalkyl) sugar reagent
    Patent number: 5491083
    Abstract: Poly(fluoroalkyl) sugar reagents are prepared containing a sugar such as a monosaccharide or a disaccharide to which are bonded a plurality of fluoroalkyl anchor groups capable of attaching to a fluorocarbon surface, and either a reactive group capable of covalent coupling to a biomolecule such as an enzyme or a charged group to form an ion-exchanger or a non-ionic group to give a neutral fluorosurfactant. A spacer may be between the reactive group and the sugar. The poly(fluoroalkyl) sugar reagents are strongly adsorbed onto fluorocarbon surfaces to provide supports for such applications as separation and immobilization of biomolecules such as enzymes, carrying out heterogeneous diagnostic assays, and preparation of biosensors.
    Type: Grant
    Filed: October 5, 1994
    Date of Patent: February 13, 1996
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Rene Arentzen, Prabhakar K. Jadhav, Robert K. Kobos, Bruce E. Smart

  • Poly(fluoroalkyl) sugar reagents for surface modification of supports
    Patent number: 5243037
    Abstract: Poly(fluoroalkyl) sugar reagents are prepared containing a sugar such as a monosaccharide or a disaccharide to which are bonded multiple fluoroalkyl anchor groups capable of attaching to a fluorocarbon surface, and either a reactive group capable of covalent coupling to a biomolecule or a charged group to form an ion-exchanger or a non-ionic group to give a neutral fluorosurfactant. A spacer may be between the reactive group and the sugar. The poly(fluoroalkyl) sugar reagents are strongly adsorbed onto fluorocarbon surfaces to provide supports for such applications as separation and immobilization of biomolecules such as enzymes, carrying out heterogeneous diagnostic assays, and preparation of biosensors.
