摘要: Methods and apparatus for detecting electrical short circuits in fuel cell stacks are provided. The methods involve supplying a reactant and an inert gas to a fuel cell stack and measuring the open circuit voltage of fuel cell assemblies in the fuel cell stack. The sensitivity of the methods can be adjusted to detect an electrical short circuit having a resistance at or below a particular threshold short-circuit resistance value, by using a suitable reactant concentration in the method. The methods can include determining a set-point reactant concentration that can be used to detect an electrical short circuit having a resistance at or below a particular threshold short-circuit resistance value.

摘要: A test cartridge includes a membrane separating an internal space of the cartridge into a sample chamber and a second chamber. A first electrode is disposed within the sample chamber, and a second electrode is disposed within the second chamber. A device includes a dock and circuitry. The dock includes a first dock-terminal and a second dock-terminal, and is configured to receive the cartridge such that the circuitry is electrically connected to the electrodes via contact between terminals of the dock and terminals of the cartridge. The circuitry performs, while the cartridge remains docked with the dock: (a) a verification step that verifies an absence of nanopores in the membrane, (b) subsequently, a nanoporation subroutine, and (c) subsequently, an assay subroutine. The circuitry enables the nanoporation subroutine only if the verification step successfully verifies the absence of nanopores. Other embodiments are also described.

摘要: A method of making a nanostructured palladium thin film electrode is described. The method involves contacting a substrate with an aerosol comprising a solvent and a Pd(II) compound. The substrate is heated, and no hydrogen gas or an additional reducing agent is required to reduce the Pd(II) to form the deposited thin film. The nanostructured palladium thin film electrode is capable of detecting compounds such as hydrazine in an aqueous sample with a 10 nM limit of detection.

摘要: There is provided a method for measuring an antigen, comprising: providing a solution containing an antigen; providing a first antibody that specifically recognizes the antigen and is bound to a magnetic carrier; providing a second antibody that specifically recognizes the antigen and is modified with an oxidase; providing (a substrate liquid including) a substrate which reacts with the oxidase; allowing the first antibody to recognize the antigen; allowing the second antibody to recognize the antigen; using a magnetic field to capture an antigen-antibody complex of the antigen recognized by the first antibody and the second antibody in the magnetic field; washing the antigen-antibody complex while it is captured in the magnetic field; reacting the substrate with the antigen-antibody complex to produce hydrogen peroxide; and measuring the hydrogen peroxide.

摘要: Methods and apparatuses relating to large scale FET arrays for analyte detection and measurement are provided. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes.

摘要: Embodiments in accordance with the present disclosure are directed to methods and apparatuses used for evaluating a protein in a sample using proteolysis and translocation. An example method includes isolating a single protein from a sample in a chamber having at least a first well and a second well separated from the first well by a membrane with a nanopore, the nanopore providing fluidic communication between the first and second wells. The single protein is cleaved into a plurality of peptide fragments via exposure to a protease in the first well, and translocated through the nanopore by applying an electric potential to the nanopore in the chamber after cleavage of the single protein by the protease. The method further includes detecting events indicative of the translocations of the plurality of peptide fragments through the nanopore and to the second well.

摘要: The invention provides a novel microfluidic platform for use in electro-crystallization and electro-crystallography experiments. The manufacturing and use of graphene as X-ray compatible electrodes allows the application of electric fields on-chip, during X-ray analysis. The presence of such electric fields can be used to modulate the structure of protein (or other) molecules in crystalline (for X-ray diffraction) or solution form (for X-ray scattering). Additionally, the presence of an electric field can be used to extend the lifetime of fragile samples by expediting the removal of reactive secondary radiation damage species.

摘要: A method for preparing a label-free aptamer electrochemical sensor of γ-interferon based on a dendrimer/gold nanoparticle/molybdenum disulfide nanocomposite is provided. The nanocomposite is drip-coated on a surface of an electrode to prepare a modified electrode, and a terminal sulfhydryl group of a γ-interferon aptamer chain is connected to the gold nanoparticle via Au—S bond to obtain a nanocomposite-aptamer modified electrode. When γ-interferon is present, the γ-interferon specifically binds to the aptamer chain on the sensor, resulting in the aptamer's hairpin structure being opened and stretched, which can effectively adsorb methylene blue MB in the electrolyte, causing significant enhancement of MB redox signal. A linear relationship between a current intensity of MB oxidation peak and a concentration of the γ-interferon is fitted to construct the label-free aptamer electrochemical sensor of γ-interferon.
