  • Nanoparticle polyanion conjugates and methods of use thereof in detecting analytes
    Publication number: 20080153082
    Abstract: This invention provides polyanionic polymer conjugates containing non-nucleotide polyanionic polymers that are useful in detecting target analytes such as proteins or small molecules. The invention also provides nanoparticles bound to polyanionic polymer conjugates and methods of preparation and use thereof. The polyanionic polymer conjugates have the formula: L-O—[PO2—O-Z-O]n—PO2—O—X wherein n ranges from 1 to 200; L represents a moiety comprising a functional group for attaching the polyanion polymer to the nanoparticle surface; Z represents a bridging group, and X represents Q, X? or -Q-X?, wherein Q represents a functional group for attaching a recognition probe to the polyanion polymer, and X? represents a recognition probe.
    Type: Application
