  • Patent number: 11879116
    Abstract: A method of analysing nucleic acid using apparatus comprising a reaction chamber and plurality of sensors located in the base of the chamber, with each sensor preferably located within a respective well. The method comprises flowing a fluid containing the nucleic acid or fragments thereof into the reaction chamber. While the chamber is fully or at least partially sealed, amplification of the nucleic acid or said fragments is performed within the chamber using an amplification primer or primers whilst detecting the generation of amplicons using said sensors. Sequencing or hybridisation is then performed on the amplicons, and sequencing or hybridisation is detected using said sensors.

  • Patent number: 11073513
    Abstract: The invention generally relates to using magnetic particles and alternating magnet fields to separate a target analyte from a sample. In certain embodiments, methods of the invention involve contacting a sample with magnetic particles including first moieties specific for a target analyte, thereby forming target/particle complexes in the sample, flowing the sample through a channel including second moieties attached to at least one surface of the channel, applying alternating magnetic fields to the flowing sample to result in target/particle complexes being brought into proximity of the surface to bind the second moieties and unbound particles remaining free in the sample, binding the target/particle complexes to the second moieties, and washing away unbound particles and unbound analytes of the sample.

  • Patent number: 10745763
    Abstract: The invention generally relates to a system for isolating or separating a target from a sample. In certain aspects, processes performed by the target capture system include introducing a plurality of magnetic particles, in which a plurality of the particles include at least one binding moiety specific to a target, into a sample to form at least one target/particle complex and applying a magnetic field to isolate the magnetic particle/target complexes from the sample. The process starts at inputting a sample into the system and ends at delivering a capture target or nucleic acids of the target into a container for further analysis.

  • Patent number: 10697011
    Abstract: An apparatus with a transducer having a first output signal and arranged to receive an electrical input. The transducer switches the first output signal between an ON and OFF state. The apparatus has a chemical sensing surface coupled to the transducer arranged to receive a chemical input. A signal generator oscillates one or more of said inputs to vary the switching point of the transducer. The oscillating input may be the chemical input and/or the electrical input. The output signal may be a pulse whose period ON or OFF is determined by the oscillating input modulated by the chemical input.
