    摘要: The invention provides methods for analyzing the protein content of a biological sample, for example to obtain a protein profile of a sample provided by a particular individual. The proteins and protein fragments in the sample are separated on the basis of chemical and/or physical properties and maintained in a separated state at discrete locations on a solid substrate or within a stream of flowing liquid. Raman spectra are then detected as produced by the separated proteins or fragments at the discrete locations such that a spectrum from a discrete location provides information about the structure or identity of one or more particular proteins or fragments at the discrete location. The proteins or fragments at discrete locations can be coated with a metal, such as gold or silver, and/or the separated proteins can be contacted with a chemical enhancer to provide SERS spectra. Method and kits for practicing the invention are also provided.

    摘要: The present methods and apparatus concern nucleic acid sequencing by incorporation of nucleotides into nucleic acid strands. The incorporation of nucleotides is detected by changes in the mass and/or surface stress of the structure. In some embodiments of the invention, the structure comprises one or more nanoscale or microscale cantilevers. In certain embodiments of the invention, each different type of nucleotide is distinguishably labeled with a bulky group and each incorporated nucleotide is identified by the changes in mass and/or surface stress of the structure upon incorporation of the nucleotide. In alternative embodiments of the invention only one type of nucleotide is exposed at a time to the nucleic acids. Changes in the properties of the structure may be detected by a variety of methods, such as piezoelectric detection, shifts in resonant frequency of the structure, and/or position sensitive photodetection.

    摘要: Composite organic-inorganic nanoclusters (COINs) are provided that produce surface-enhanced Raman signals (SERS) when excited by a laser. The nanoclusters include metal particles and a Raman-active organic compound. The metal required for achieving a suitable SERS signal is inherent in the nanocluster and a wide variety of Raman-active organic compounds and combinations thereof can be incorporated into the nanocluster. In addition, polymeric microspheres containing the nanoclusters and methods of making them are also provided. The nanoclusters and microspheres can be used, for example, in assays for multiplex detection of biological molecules.

    摘要: Methods and apparatuses for sequencing single polymer molecules, such as a nucleic acid strand, are discussed. A discussed method comprises dividing a polymer sample into a number of polymer subsamples equal to the number of different monomer types and partially labeling only one of the monomer types in each polymer subsample. The method may further comprise placing a subsample into a reaction chamber, sequentially separating each monomer from the polymer subsample, and detecting the labels of each separated labeled monomer as a function of time. The time between each labeled monomer may be used to construct a monomer-time map for each polymer sub-sample using overlapping data analysis and frequency analysis. Time maps may then be assembled/aligned into a polymer sequence from the monomer-time maps of each of the polymer subsamples using non-overlapping data analysis.

    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.
