    摘要: Provided herein, is a nucleic acid sequencing method based on detection of Raman signatures of oligonucleotide probes. Raman signatures of individually captured nucleic acid probes, optionally labeled by a Raman label or a positively charged enhancer, are detected. The sequences of captured probes are used to identify the nucleotide sequences of captured probes and complementary target nucleic acids, which are then aligned and used to obtain nucleic acid sequence information. In another embodiment, a method is provided for determining a nucleotide occurrence at a target nucleotide position of a target nucleic acid, that utilizes binding of the target nucleic acid to a labeled oligonucleotide probe that binds to the target nucleic acid, wherein the labeled oligonucleotide probe includes a first label and a second label, the first label being capable of affecting an optical property of the second label.

    摘要: The present disclosure concerns methods for producing and/or using molecular barcodes. In certain embodiments of the invention, the barcodes comprise polymer backbones that may contain one or more branch structures. Tags may be attached to the backbone and/or branch structures. The barcode may also comprise a probe that can bind to a target, such as proteins, nucleic acids and other biomolecules or aggregates. Different barcodes may be distinguished by the type and location of the tags. In other embodiments, barcodes may be produced by hybridization of one or more tagged oligonucleotides to a template, comprising a container section and a probe section. The tagged oligonucleotides may be designed as modular code sections, to form different barcodes specific for different targets. In alternative embodiments, barcodes may be prepared by polymerization of monomeric units. Bound barcodes may be detected by various imaging modalities, such as, surface plasmon resonance, fluorescent or Raman spectroscopy.

    摘要: SERS technology is used for high throughput screening of biological analytes and samples. For polynucleotide sequencing, sets of oligonucleotide probes are labeled with composite organic-inorganic nanoparticles (COIN) that produce distinguishable SERS signals when excited by a laser. Detection of a hybridization complex containing members of two such COIN-labeled probe sets will reveal a 12 nucleotide sequence segment of the target polynucleotide. Also provided are surface-modified arrays and chips with multiple arrays to which sets of probe-conjugated COIN or other reporter substrates are immobilized. Analytes are detected by contacting a sample, such as a bodily fluid, with the array-anchored probes. Captured analytes are tagged with an additional target-specific Raman-active tag. Two or more Raman signatures emanating from the detection complexes reveal the identity of the captured analytes.
