  • Patent number: 10871461
    Abstract: A method for accurately measuring the conductivity of substances. This method incorporates two points of measurement that are isolated from each other. Each of these points is in contact with the substance to be measured. A continuous, constant electrical current is passed through the substance at the measurement points by means of an electrical force that is not constant but varies depending upon the amount of electrical force required to maintain the constant electrical current through the substance. This constant current is passed through the substance in two directions. This change in direction is achieved by reversing the polarity of the electrical force across the two measurement points. The time periods for each of the two directions of constant current flow are equal. The amount of electrical force or voltage that is required to maintain this constant amount of current is directly related to the resistance of the substance.

    Abstract: Methods of detecting target nucleic acid is a sample are described. A first probe is attached to first beads, and the first beads are placed in the sample so that any target nucleic acid attaches to the first probe. A second probe also attaches to the target nucleic acid so that any of the target nucleic acid links or “tethers” the first and second probes. A capacitive sensor detects capacitance of the beads and processes capacitance data to quantify target nucleic acid presence in the sample. The second probe may be immobilised on the sensor surface. Alternatively the second beads are introduced into the sample with the second probe attached, and the extent of tethering of the first beads to the second beads is indicative of the extent of target NA present.

    Abstract: A system, device and apparatus for measuring electrolytes, where an electrical charge is applied to a measurement portion to draw ions from a liquid to a gel-solution via at least one electric field. The gel-solution containing the extracted ions is excited with light of a predetermined wavelength from an emitter. A receiver detects the illumination of the ions as a result of the excited gel-solution, and a processor converts the detected intensities of the illumination to a biologically useful value representing ionic concentration.

  • Patent number: 10690528
    Abstract: An electrochemical sensor may measure the flow of ions and/or electrochemical species in a solution passing the sensor because the electroactive species will continually come into contact with the electrode and an electric signal will be generated by the combination of diffusion and convection bringing the electroactive species to the electrode. The electric signal measured will vary by concentration of ions and/or electrochemical specie(s) and by flow rate. Flow rate may be measured if the concentration of ions and/or electrochemical specie(s) is known; conversely, the concentration of ions and/or electrochemical species may be measured if the flow rate is known. The sensor may also be used to confirm the delivery of a fluid containing ions and/or electrochemical specie(s).

  • Patent number: 10671678
    Abstract: The present invention provides a surface acoustic wave sensor capable of suitably controlling the flow of a liquid sample onto IDT electrodes. A surface acoustic wave sensor has a piezoelectric substrate, a first IDT electrode and a second IDT electrode which are located on the upper surface of the piezoelectric substrate and are separated from each other while sandwiching a detection part on the piezoelectric substrate therebetween, and the cover which forms the space being on the first IDT electrode, second IDT electrode, and the detection part and straddling them. On the lower surface of the cover, the detection part-facing surface facing the detection part has a smaller contact angle to the liquid sample than that of a pair of electrode-facing surfaces facing the first IDT electrode and second IDT electrode.

  • Patent number: 10591405
    Abstract: A method for testing an electrochemical response of a sample, which is at least partially disposed within an electrolyte, includes macro scanning the sample. Macro scanning is applied across the entire sample and includes applying a first range of macro potential between the electrolyte and the sample, and measuring a first range of macro current between the electrolyte and the sample, while subject to the first range of macro potential. The macro scan is held at a first fixed macro potential within the first range of macro potential and the sample is micro scanned while held at the first fixed macro potential. Micro scanning is applied at individual points across a surface portion of the sample and includes measuring a plurality of first micro currents at each of the individual points of the surface portion of the sample. Each individual point is significantly smaller than the entire sample.
