    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: The methods and apparatus disclosed herein concern nucleic acid sequencing by enhanced Raman spectroscopy. In certain embodiments of the invention, nucleotides are covalently attached to Raman labels before incorporation into a nucleic acid. In other embodiments, unlabeled nucleic acids are used. Exonuclease treatment of the nucleic acid results in the release of labeled or unlabeled nucleotides that are detected by Raman spectroscopy. In alternative embodiments of the invention, nucleotides released from a nucleic acid by exonuclease treatment are covalently cross-linked to nanoparticles and detected by surface enhanced Raman spectroscopy (SERS), surface enhanced resonance Raman spectroscopy (SERRS) and/or coherent anti-Stokes Raman spectroscopy (CARS). Other embodiments of the invention concern apparatus for nucleic acid sequencing.

    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 methods and apparatus disclosed herein are useful for detecting nucleotides, nucleosides, and bases and for nucleic acid sequence determination. The methods involve detection of a nucleotide, nucleoside, or base using surface enhanced Raman spectroscopy (SERS) or surface enhanced coherent anti-Stokes Raman spectroscopy (SECARS). The detection can be part of a nucleic acid sequencing reaction to detect uptake of a deoxynucleotide triphosphate during a nucleic acid polymerization reaction, such as a nucleic acid sequencing reaction. The nucleic acid sequence of a synthesized nascent strand, and the complementary sequence of the template strand, can be determined by tracking the order of incorporation of nucleotides during the polymerization reaction. Methods for enhancing the SERS signal of a nucleotide or nucleoside by cleaving the base from a sugar moiety are provided. Furthermore, methods for detecting single base repeats are provided.
