  • Patent number: 8128890
    Abstract: The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and algorithms disclosed herein largely overcome these limitations. Briefly, all cells in a biological sample are fluorescently labeled, but only the target cells are also magnetically labeled. The labeled sample, in a chamber or cuvet, is placed between two wedge-shaped magnets to selectively move the magnetically labeled cells to the observation surface of the cuvet. An LED illuminates the cells and a CCD camera captures the images of the fluorescent light emitted by the target cells.

  • Patent number: 8067246
    Abstract: A method and apparatus for use in a flow through assay process is disclosed. The method is characterised by a “pre-incubation step” in which the sample which is to be analyzed (typically for the presence of a particular protein), and a detection analyte (typically one or more antibodies bound to colloidal gold or a fluorescent tag) which is known to bind to the particular protein may bind together for a desired period of time. This pre-incubation step occurs before the mixture of sample and detection analyte come into contact with a capture analyte bound to a membrane. The provision of the pre-incubation step has the effect of both improving the sensitivity of the assay and reducing the volume of sample required for an assay. An apparatus for carrying out the method is disclosed defining a pre-incubation chamber for receiving the sample and detection analyte having a base defined by a membrane and a second membrane to which a capture analyte is bound.

That is, a reaction detection plate is used to transmit a signal detected in the sensor element via a reader coil and a reader and then analyze the reaction. The reaction detection plate has a) a membrane, b) a first antibody impregnated section that is disposed such that it faces the membrane and holds a first labeled antibody that specifically binds to a substance to be analyzed, c) a second antibody immobilized section that is provided in part of the membrane and has an immobilized second antibody, the second antibody specifically binding to the substance to be analyzed, and d) a sensor element that is disposed such that it faces the second antibody immobilized section and includes a light detector and a signal transceiver.

  • Patent number: 7981382
    Abstract: A device for collecting, testing and storing fluids includes a container and a removable cap. Body fluids, such as urine, are collected in the container. The cap defines a test strip holder that receives one or more drug test strips and an adulteration strip. An opening defined through a bottom of the cap provides fluid communication between the container and the cap. When tilted, fluid from the container enters the cap through the hole. A variety of plugs may be employed to block the opening and thereby prevent fluid communication between the container and the cap after fluid has entered the cap. The remaining uncontaminated and untested body fluid is stored in the container and thus made available for further confirmation testing. Associated methods for collecting, testing and storing fluids with a single device are also provided. A method of manufacturing the foregoing test device is also provided.

  • Patent number: 7976467
    Abstract: A meter is provided that includes an improved user interface that enables the user to take a specific action, leading them directly to data input options. Such a user interface could be used to input first selected information, such as whether a test was premeal or postmeal, immediately after receiving a result. Optionally, the user interface may include the ability to add an additional comment after inputting the first selected information. Provision of such a user interface would facilitate simpler capture of the first selected information each time the user performs a test, leading to an enhanced understanding of a patient's level of glycemic control. Designing a user interface to enable first selected information to be entered by a user directly after receiving a result is more likely to engage a patient by making it easy and simple to enter important information. This may enable capture of the information thought to be most pertinent e.g.

  • Patent number: 7959873
    Abstract: A biosensor is comprised of a free and a biofunctionalized recognition self-sensing nanocantilever, a dock adjacent to the ends of the nanocantilevers, and a gap between the nanocantilevers and dock. The self-sensing cantilevers each include a semiconductor piezoresistor defined in a pair of legs about which the cantilevers flex. A bias power or current is applied to the piezoresistor. The sensitivity of the cantilevers is optimized for a given ambient temperature and geometry of the cantilevers and dock by minimizing the force spectral density, SF, of the cantilevers to determine the optimum bias power, Pin. A sub-aN/?Hz force sensitivity is obtained by scaling down the dimensions of the cantilevers and supplying an optimum bias power as a function of temperature and geometry.

  • Patent number: 7939030
    Abstract: The present invention provides a micro mechanical system for performing assays for determining the presence of one or more selected analytes in a sample. The device comprises of a base and a disposable strip with at least one reaction well and at least one moveable member capable of moving fluids and parts through the fluids in a defined reaction well. Reagents in the reaction chambers and or the moveable members, react with the sample to yield a physically detectable change. The moveable parts are capable of executing motions that either mix, move reaction components, exchange or systematically deliver reagents to targets in the cartridge. Sensors in the base are configured to detect and or quantify the presence of a sample in the reaction well and of analytes in the sample. The signal is converted to an output on a visual display window on the external part of the base.

  • Patent number: RE42924
    Abstract: An electrochemical biosensor test strip with four new features. The test strip includes an indentation for tactile feel as to the location of the strips sample application port. The sample application port leads to a capillary test chamber, which includes a test reagent. The wet reagent includes from about 0.2% by weight to about 2% by weight polyethylene oxide from about 100 kilodaltons to about 900 kilodaltons mean molecular weight, which makes the dried reagent more hydrophilic and sturdier to strip processing steps, such as mechanical punching, and to mechanical manipulation by the test strip user. The roof of the capillary test chamber includes a transparent or translucent window which operates as a “fill to here” line, thereby identifying when enough test sample (a liquid sample, such as blood) has been added to the test chamber to accurately perform a test. The test strip may further include a notch located at the sample application port. The notch reduces a phenomenon called “dose hesitation”.
