  • Patent number: 6855523
    Abstract: An improved method allowing for rapid sensitive and standardized detection of a target nucleic acid from a pathogenic microorganism or virus or normal or abnormal gene in a sample is provided. The method involves hybridizing a target nucleic acid to several non-overlapping oligonucleotide probes that hybridize to adjacent regions in the target nucleic acid, the probes being referred to capture/amplification probes and amplification probes, respectively, in the presence of paramagnetic beads coated with a ligand binding moiety. Through the binding of a ligand attached to one end of the capture/amplification probe and the specific hybridization of portions of the probes to adjacent sequences in the target nucleic acid, a complex comprising the target nucleic acid, the probes and the paramagnetic beads is formed. The probes may then ligated together to form a contiguous ligated amplification sequence bound to the beads, which complex may be denatured to remove the target nucleic acid and unligated probes.

  • Publication number: 20030236205
    Abstract: The present invention relates to a hybridization signal amplification method (HSAM) that can be used to form nanostructures for use in drug delivery and diagnostics and may comprise molecules aimed at a specific target cell of interest. The nanostuctures may be used to treat infectious diseases and physiological disorders such as proliferative, genetic, neurological or metabolic disorders. The nanostructures of the invention comprise nucleic acid molecules having affinity pairs incorporated into their structure. These affinity pairs are formed from ligand and ligand binding moieties that bind to nucleic acid molecules. This bound entity is a complex, web-like structure that serves as a matrix or framework for delivery of therapeutic or diagnostic agents. Since the nanostructures of the invention are comprised of biocompatible and biodegradable materials, such as nucleic acid molecules and proteins, they provide a safe and easily degradable delivery system.
