  • Patent number: 10094824
    Abstract: The present invention concerns a device for measuring the concentration of analytes in liquid samples such as bodily samples. The device comprises an application zone, to which a sample can be applied, and which contains a specific molecule capable of specifically binding the analyte of interest, said specific molecule being conjugated to a reporter which can give rise to variations in impedance. The resulting complex migrates by capillarity and enters a detection zone, on which another molecule capable of specifically binding the analyte of interest is immobilized. The concentration of reporter molecules in the detection zone is proportional with the concentration of analyte in the sample, and variations in concentration of reporter molecules yield a measurable change in electrical properties such as a change in impedance and/or capacitance which can be correlated to the concentration of analyte.

  • Patent number: 9939440
    Abstract: A method and apparatus for electrochemical detection of analyte in a sample makes use of a binding interaction and relies on the discovery that asymmetric distribution of a redox enzyme between two electrodes that occurs when a redox enzyme-containing reagent is immobilized at the surface of one electrode can be detected as a chemical potential gradient arising from an asymmetry in the distribution of oxidized or reduced redox substrate. This chemical potential gradient can be detected potentiometrically by observing the potential difference between the electrodes in an open circuit, or amperometrically by observing the current flow between the electrodes when the circuit is closed. In both cases, the observation of asymmetry can be done without the application of an external potential or current to the electrodes.

  • Patent number: 9017526
    Abstract: The disclosed embodiments relate to methods and apparatus for removing material from a substrate. In various implementations, conductive material is removed from a sidewall of a previously etched feature such as a trench, hole or pillar on a semiconductor substrate. In practicing the techniques herein, a substrate is provided in a reaction chamber that is divided into an upper plasma generation chamber and a lower processing chamber by a corrugated ion extractor plate with apertures therethrough. The extractor plate is corrugated such that the plasma sheath follows the shape of the extractor plate, such that ions enter the lower processing chamber at an angle relative to the substrate. As such, during processing, ions are able to penetrate into previously etched features and strike the substrate on the sidewalls of such features. Through this mechanism, the material on the sidewalls of the features may be removed.

  • Patent number: 8529759
    Abstract: An electric deionized water production apparatus in which a direct current field is applied to a deionizing chamber packed with an ion-exchange material such that ions to be discharged are allowed to migrate in the direction identical or opposite to the direction of the water flow in the ion-exchange material, whereby ionic impurities adsorbed in the ion-exchange material are discharged from the system, the ion-exchange material being a mixture of a monolith-shaped organic porous ion-exchange material and ion-exchange resin particles. The electric deionized water production apparatus has a simple structure that can reduce material cost, process cost, and assembly cost, capable of accelerating migration of the adsorbed ionic impurities to facilitate discharge of the adsorbed ions and free from a deflected flow due to swelling or shrinkage accompanying an ion-exchanging reaction, and from poor contact with an ion-exchange membrane.

  • Patent number: 8415645
    Abstract: It is aimed to prevent electrical charging inside a resin material as well as a surface of a resin vessel at a time of sterilizing the resin vessel by being irradiated with electron beam. A bottle support unit is mounted to a lower end portion of a cylindrical rotating shaft rotatably supported by a rotating wheel. The bottle support unit includes a pair of griper members by which a mouth portion of a bottle is gripped. The bottle rotated and conveyed in a state supported by the bottle support unit is irradiated with the electron beam from an electron beam irradiator to thereby sterilize the bottle. A ground electrode is disposed to be capable of being inserted into the interior of the resin vessel through a mouth portion thereof, and the interior of the resin vessel is irradiated with the electron beam in a state of the ground electrode being inserted into the resin vessel.

  • Patent number: 8327460
    Abstract: The present invention allows simple and sensitive detection of microimpurities, microdefects, and corrosion starting points which may be present in a material. A probe microscope has a function to sense ions diffused from a specimen in a liquid. A probe is caused to scan over a predetermined range on a specimen. Then, the probe is fixed to a particular position in a liquid so as to set the distance between the specimen and the probe to a given value at which the microstructure of the specimen surface cannot be observed. Thereafter, one of the current between the probe and a counter electrode and the potential between the probe and a reference electrode is controlled, and the other of the current and potential which varies in accordance with the control is measured. Thus, ions diffused from the specimen are sensed.

  • Patent number: 8231786
    Abstract: Water treatment method and apparatus according to which supply water containing dissolved matter is delivered to at least one treatment surface. An electric field is created in the vicinity of the treatment surface to cause a hydration layer to be established due to the bipolar nature of the water molecules. Water is then extracted from the hydration layer. Such extraction may be effected by osmosis or by removal of the element (s) from the supply water with the hydration layer water thereon, dehydration layer water subsequently being extracted from the element (s). The method has been devised to reduce energy consumption for the purpose of providing potable water from seawater.
