  • Patent number: 10689697
    Abstract: Analysis Of A Polymer A biochemical analysis system analyses polymers by taking measurements of a polymer from a sensor element comprising a nanopore during translocation of the polymer through the nanopore. When a polymer has partially translocated, the series of measurements is analysed using reference data derived from a reference sequence to provide a measure of similarity. Responsive to the measure of similarity, the sensor element may be selectively operated to eject the polymer and thereby make the nanopore available to receive a further polymer. Where the biochemical analysis system comprises an array of sensor elements and is takes measurements from sensor elements selected in a multiplexed manner, responsive to the measure of similarity, the biochemical analysis system ceases taking measurements from the currently selected sensor element and to starts taking measurements from a newly selected sensor element.

  • Patent number: 10569225
    Abstract: A technique for separating components of a microfluid, comprises a self-intersecting micro or nano-fluidic channel defining a cyclic path for circulating the fluid over a receiving surface of a fluid component separating member; and equipment for applying coordinated pressure to the channel at a plurality of pressure control areas along the cyclic path to circulate the fluid over the receiving surface, applying a pressure to encourage a desired transmission through the separating member, and a circulating pressure to remove surface obstructions on the separating member. The equipment preferably defines a peristaltic pump. Turbulent microfluidic flow appears to be produced.

  • Patent number: 10564077
    Abstract: A device and a method are provided for isolating a fraction in a biological sample. The fraction is bound to solid phase substrate to define a fraction-bound solid phase substrate. The device includes an input zone for receiving the biological sample therein to capture a desired fraction of the biological sample. A force is provided that is generally perpendicular to gravity. The force is movable between a first position adjacent the input zone multiple other positions adjacent various purification, protein analysis, separation and extraction zones. The force captures the fraction-bound solid phase substrate and the fraction-bound solid phase substrate moves from the input zone to the other zones to perform a multi-step assay on the isolated fraction within the device.

  • Patent number: 10550392
    Abstract: The present invention provides synthetic DNA aptamers that bind a target explosive to allow detection of that explosive. In various embodiments, the synthetic DNA aptamers may include one or more aptamers selected from the group consisting of SEQ ID 1-6. The various synthetic DNA aptamers are sensitive to different explosives. The synthetic DNA aptamers provide an inexpensive, in situ means for testing for explosive, which may be used for both soil and water samples. This testing may include an assay method using the synthetic DNA aptamers or a biosensor linked to the synthetic DNA aptamers.

  • Patent number: 10227633
    Abstract: The present disclosure provides a portable device for purifying biological sample. The device comprises a housing and a cartridge holder accommodated in the housing for holding at least one cartridge configured to purify the biological sample. At least one pump is positioned in the housing which is fluidly connectable to the cartridge to circulate the sample and one or more fluids through the cartridge. Further, at least one heating element is configured to heat a matrix chamber in the cartridge. At least one actuator is disposed in the housing to actuate one or more valves to selectively route the biological sample and the one or more fluids in the cartridge. A control unit is interfaced with the actuator, the heating element and the pump and is configured to regulate operation of the actuator, the pump and the heating element during purification of the biological sample.

  • Patent number: 10217620
    Abstract: Hepatocellular carcinoma (HCC) is detected in a patient with liver disease. Mass spectrometry data from a blood-based sample from the patient is compared to a reference set of mass-spectrometry data from a multitude of other patients with liver disease, including patients with and without HCC, in a general purpose computer configured as a classifier. The classifier generates a class label, such as HCC or No HCC, for the test sample. A laboratory system for early detection of HCC in patients with liver disease is also disclosed. Alternative testing strategies using AFP measurement and a reference set for classification in the form of class-labeled mass spectral data from blood-based samples of lung cancer patients are also described, including multi-stage testing.
