Publication number: 20200002745Abstract: A cartridge interface module (CIM), configured to engage with a removable microfluidic cartridge in a nucleic acid analyzer system can include a fluidics component, which is configured to initiate and support a liquid extraction of nucleic acids from a biological sample contained in the removable microfluidic cartridge. The CIM also includes a polymerase chain reaction (PCR) assembly component which can be configured to initiate and support amplification of the extracted nucleic acids. The CIM may also include a high voltage electrodes component that is configured to initiate and support separation of the amplified nucleic acids into nucleic acid fragments in a separation channel of the removable microfluidic cartridge. The CIM also includes a detection optics component that can be configured to collect, detect, and direct label nucleic acid fragments. The CIM is configured to integrate with a microfluidic chip architecture of an inserted removable microfluidic cartridge.Type: ApplicationFiled: February 7, 2019Publication date: January 2, 2020Applicants: LOCKHEED MARTIN CORPORATION, ZYGEM CORPORATION LTD.Inventors: Michael Edward EGAN, Orion N.

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.

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.

Publication number: 20150151302Abstract: A microfluidic chip includes one or more reaction chambers to hold fluids for chemical or biochemical reactions, such as PCR. A non-contact heat source heats the reaction chamber and the fluid, such that the heat source does not contact the reaction chamber or the fluid. The heat source can heat the reaction chamber and the fluid separately, where the reaction chamber and the fluid separately absorb heat radiation from the heat source. A temperature sensor acquires a temperature of the reaction chamber and/or the fluid. Control circuitry controls the heat source according to a cycling profile for the reaction in the fluid to cycle the heat source between heating and not heating the reaction chamber and the fluid based on the temperature acquired by the temperature sensor. Cooling can be provided passively or actively.Type: ApplicationFiled: December 4, 2013Publication date: June 4, 2015Applicants: ZyGEM CORPORATION LTD., LOCKHEED MARTIN CORPORATIONInventors: Michael Edward EGAN, Peter Karl Trost, James Landers, Brian Root, Orion Scott

Patent number: 8961764Abstract: A DNA analyzer includes an interface for coupling a microfluidic chip to the DNA analyzer. The microfluidic chip includes a first separation channel for electrophoretic separation of DNA fragments in a first sample. Further, the DNA analyzer includes a first optical device. The first optical device includes an illuminating path and a detecting path. The illuminating path directs a first input light beam received from a light source to a first separation channel of the microfluidic chip. The first input light beam causes fluorescent labels attached on DNA fragments in the first separation channel to emit a first fluorescence light. The detecting path collects and directs the first fluorescent light to a first plurality of optical fibers. Further, the DNA analyzer includes a spectrometer configured to receive the first fluorescent light from the plurality of optical fibers and detect fluorescent components in the first fluorescent light.Type: GrantFiled: October 14, 2011Date of Patent: February 24, 2015Assignees: Lockheed Martin Corporation, ZyGEM Corporation, Ltd.Inventors: Peter Karl Trost, Michael E.
