Patent number: 7776547Abstract: Methods and apparatus are provided for assaying cell samples, which may be living cells, using probes labeled with composite organic-inorganic nanoparticles (COINs) and microspheres with COINs embedded within a polymer matrix to which the probe moiety is attached. COINs intrinsically produce SERS signals upon laser irradiation, making COIN-labeled probes particularly suitable in a variety of methods for assaying cells, including biological molecules that may be contained on or within cells, most of which are not inherently Raman-active. The invention provides variations of the sandwich immunoassay employing both specific and degenerate binding, methods for reverse phase assay of tissue samples and cell microstructures, in solution displacement and competition assays, and the like. Systems and chips useful for practicing the invention assays are also provided.Type: GrantFiled: December 30, 2004Date of Patent: August 17, 2010Assignee: Intel CorporationInventors: Mark Roth, Andrew Berlin, Selena Chan, Tae-Woong Koo, Xing Su, Lei Sun

Patent number: 7465578Abstract: The methods, compositions and apparatus disclosed herein are of use for nucleic acid sequence determination. The methods involve isolation of one or more nucleic acid template molecules and polymerization of a nascent complementary strand of nucleic acid, using a DNA or RNA polymerase or similar synthetic reagent. As the nascent strand is extended one nucleotide at a time, the disappearance of nucleotide precursors from solution is monitored by Raman spectroscopy or FRET. The nucleic acid sequence of the nascent strand, and the complementary sequence of the template strand, may be determined by tracking the order of incorporation of nucleotide precursors during the polymerization reaction. Certain embodiments concern apparatus comprising a reaction chamber and detection unit, of use in practicing the claimed methods. The methods, compositions and apparatus are of use in sequencing very long nucleic acid templates in a single sequencing reaction.Type: GrantFiled: July 7, 2004Date of Patent: December 16, 2008Assignee: Intel CorporationInventors: Andrew Berlin, Steven J.
