polymer prodrug nanoparticles of average diameter in the 100-180 nm range with narrow particle size distribution and variable surface amounts of biotin. Nanoparticles containing 15 wt % biotinylated polymer showed superior uptake and the highest cytotoxicity in vitro on A549 human lung cancer cells. In vivo, on A549 tumor bearing mice, biotinylated nanoparticles showed significantly higher efficacy than

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—[PO
2
—O—Z—O]
n
—PO
2
—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.
