  • Patent number: 10927366
    Abstract: Systems and methods for detecting and sequestering target analytes in a fluid sample. The system comprises a bulk specimen reservoir for receiving a liquid sample, along with paramagnetic materials operative to selectively bind to the target analyte of interest. A vertex is interconnected with the bulk specimen reservoir to define a specimen chamber assembly to which a magnetic chamber is deployed about the vertex portion thereof and operative to sequester the magnetic particles, as well as any analyte of interest bound thereto, within the interior of the vertex. Once sufficient time is allowed for mixing and allowing the magnetic capsule to sufficiently retain the magnetic particles within the vertex, the vertex is disconnected from the specimen reservoir and the paramagnetic materials retained therein analyzed to determine the presence of the analyte of interest.

  • Publication number: 20200114323
    Abstract: Systems and methods are for creating liquid toroidal mixing patterns within microliter volumes of liquids are contemplated. An electrode geometry comprising peripheral electrodes defining an annular configuration and interior electrodes are contemplated, to which an alternating current may be applied. Via control of the frequency, waveform, amplitude and bias of the current, liquids and the components of those liquids may be mixed in a toroidal motion. This same electrode geometry may also be used to accomplish the deposition of targeted materials onto the surface of the peripheral or interior electrode by further manipulating the frequency, amplitude, and bias of the waveform of the applied current. Methods of applying such techniques are also contemplated in the context of blood typing assays, latex agglutination assays, micro array assays, transfection, transduction, and tissue engineering methods, and it may be seen that such techniques may result in substantial benefits.

  • Patent number: 10585101
    Abstract: Disclosed are methods to induce dislodgement of target prostatic cells from the prostate organ, collecting said cells, and subsequently examining the cell population. Such methods comprise the administration of an agent that facilitates the dislodgement of the target cells from within the prostate, which then migrate into the urethra. Exemplary agents include 5 alpha-reductase inhibitors. The cells induced to pass into the urethra are then collected non-invasively, such as through urine or semen samples. Such collection is further strategically calculated relative the administration of the agent so as to maximize the sample collection of the target cells of interest.

  • Patent number: 7390675
    Abstract: Novel magnetic assay methods and systems. According to a preferred embodiment, a chromatographic medium is provided that is designed to be contacted with a test solution having activated magnetic particles such that the solution flows bilaterally thereacross. A magnetic field, generated by a magnet or electromagnet, is selectively applied to the medium which causes the charged particles to become substantially bound at a site on the medium specified by the position of the magnet, to thus form a captured line or zone. In one preferred embodiment, the magnetic field is applied at the site on the medium at which the test solution is contacted. The assay is multi-configurable and can be modified to suit a particular immuno-separation procedure or application.

  • Patent number: 6991912
    Abstract: Novel magnetic assay methods and systems. According to a preferred embodiment, a chromatographic medium, which preferably comprises a test strip, is provided that is designed to be contacted with a test solution having activated magnetic particles such that the solution flows bilaterally thereacross. A magnetic field, generated by a magnet or electromagnet, is selectively applied to the medium which causes the charged particles to become substantially bound at a site on the medium specified by the position of the magnet, to thus form a captured line or zone. In one preferred embodiment, the magnetic field is applied at the site on the medium at which the test solution is contacted. The degree of magnetic force applied to the membrane may be selectively adjusted to vary the width or surface area of the capture line or zone.

A magnetic field, generated by a magnet or electromagnet, is selectively applied to the medium which causes the charged particles to become substantially bound at a site on the medium specified by the position off the magnet, to thus form a captured line or zone. In one preferred embodiment, the magnetic field is applied at the site on the medium at which the test solution is contacted. The degree of magnetic force applied to the membrane may be selectively adjusted to vary the width or surface area of the capture line or zone.
