Patent number: 9988676Abstract: A microfluidic cartridge can include at least one nucleic acid analysis portion. Each nucleic acid analysis portion can include a fluidic network being configured for micro-liter volumes or less, a sample input at the beginning of the fluidic network, a plurality of vent ports and fluidic channels in the fluidic network configured to effectuate hydrodynamic movement within the fluidic network, an extraction mixture reservoir in the fluidic network, a mixing chamber in the fluidic network, an amplification chamber in the fluidic network, and a separation channel in the fluidic network. A nucleic acid analyzer can be capable of performing nucleic acid analysis using the microfluidic cartridge. A nucleic acid analysis method can be performed using the microfluidic cartridge.Type: GrantFiled: June 19, 2015Date of Patent: June 5, 2018Assignee: LEIDOS INNOVATIONS TECHNOLOGY, INC.Inventors: Michael E. Egan, Brian Root, Orion N. Scott, Douglas J. South, Joan M. Bienvenue, Paul Kinnon, James Landers, David Saul, An-Chi Tsuei, Jason Hayes, Matthew Springer, Matthew Solomon, Peter Van Ruijven

Patent number: 9656261Abstract: Aspects of the disclosure provide a microfluidic chip to facilitate DNA analysis. The microfluidic chip includes a first domain configured for polymerase chain reaction (PCR) amplification of DNA fragments, a dilution domain coupled to the first domain to dilute a PCR mixture received from the first domain, and a second domain that is coupled to the dilution domain so as to receive the amplified DNA fragments. The second domain includes a separation channel that is configured to perform electrophoretic separation of the amplified DNA fragments. In addition, the disclosure provides a DNA analyzer to act on the microfluidic chip to perform an integrated single chip DNA analysis.Type: GrantFiled: March 4, 2011Date of Patent: May 23, 2017Assignees: LEIDOS INNOVATIONS TECHNOLOGY, INC., ZyGEM CORPORATION LTD., UNIVERSITY OF VIRGINIA PATENT FOUNDATIONInventors: H. Randall Bell, Joan M Bienvenue, John W Pettit, James P Landers, Jessica V Norris, Orion N Scott, Daniel J Marchiarullo, Daniel C Leslie

Patent number: 9067207Abstract: Aspects of the disclosure provides a DNA analyzer to facilitate an integrated single-chip DNA analysis. The DNA analyzer includes an interface for coupling a microfluidic chip to the DNA analyzer. The microfluidic chip includes a first domain configured for polymerase chain reaction (PCR) amplification of DNA fragments, and a second domain fluidically coupled to the first domain to receive the DNA fragments and perform electrophoretic separation of the DNA fragments. The DNA fragments are tagged with fluorescent labels. The DNA analyzer includes a detection module to excite the fluorescent labels to emit fluorescence and detect the emitted fluorescence. The detection module includes a laser source, a set of optical elements, a filter module and a photo-detector.Type: GrantFiled: March 4, 2011Date of Patent: June 30, 2015Assignees: UNIVERSITY OF VIRGINIA PATENT FOUNDATION, ZYGEM CORPORATION LTD., Lockheed Martin CorporationInventors: H.
