Patent number: 8962279Abstract: Methods for sequencing nucleic acids are presented. Sequencing is accomplished through the chemical amplification of the products of DNA synthesis and the detection of the chemically amplified products. In embodiments of the invention, a substrate is provided having a plurality of molecules of DNA to be sequenced attached and a plurality of molecules capable of chelating pyrophosphate ions attached, the DNA molecules to be sequenced are primed, and a next complementary nucleotide is incorporated and excised a plurality of times leading to the buildup of pyrophosphate ions locally around the DNA molecule to be sequenced. Pyrophosphate ions are captured by the substrate-attached chelators and electronically detected to determine the identity of the next complementary nucleic acid in the DNA molecule to be sequenced. Additionally, devices and methods are provided for detecting biomolecules through the detection of pyrophosphate ions.Type: GrantFiled: December 30, 2009Date of Patent: February 24, 2015Assignee: Intel CorporationInventors: David J. Liu, Xing Su, Kai Wu

Publication number: 20140342470Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.Type: ApplicationFiled: July 31, 2014Publication date: November 20, 2014Inventors: Xing Su, David J. Liu, Kai Wu, Kenneth B. Swartz, Mineo Yamakawa
