Magnetic Patents (Class 210/222)
  • Patent number: 10828636
    Abstract: The invention relates to conducting assays with an apparatus including a substantially transparent assay cartridge loaded with magnetic beads, and a magnet carrier base positioned below a scanning platform holding the assay cartridge. A microcomputer controls a stepping motor which controls movement of the magnet carrier base, and causes the magnetic beads to travel from one well to another, where the wells contain different assay reagents. An electromagnetic coil-spring assembly induces mixing of well contents with the magnetic beads on actuation. The assay cartridge is authenticated by sending its encoded identifier to a server or website, and assay instructions are provided remotely to the microcomputer. Following assay completion, the cartridge can have color change or other assay indication detected, and the results sent to the server or website or another recipient. Concurrently assaying a control allows modification of assay results based on measured field conditions.

  • Patent number: 10724930
    Abstract: Sandwich separation is based on forming a sandwich complex with a magnetic bead, buoyant bead, and a target. Once a sandwich formation is created, the sandwich can be separated using its dual physical properties, namely magnetism and buoyancy. Sandwich separation is highly specific, allows for removal of the beads that do not have any attached target, and reduces the number of background beads. Sandwich separation can also be used to allow for target detection in raw specimen. Also, improvement of detection capability is accomplished by performing AMBR measurements on a solid interface, where the rotational period speeds up and allows for dramatically reduced time-to-result.

  • Patent number: 10203379
    Abstract: A method of forming a sensor array comprising a series connection of parallel GMR sensor stripes that provides a sensitive mechanism for detecting the presence of magnetized particles bonded to biological molecules that are affixed to a substrate. The adverse effect of hysteresis on the maintenance of a stable bias point for the magnetic moment of the sensor free layer is eliminated by a combination of biasing the sensor along its longitudinal direction rather than the usual transverse direction and by using the overcoat stress and magnetostriction of magnetic layers to create a compensatory transverse magnetic anisotropy. By making the spaces between the stripes narrower than the dimension of the magnetized particle and by making the width of the stripes equal to the dimension of the particle, the sensitivity of the sensor array is enhanced.

  • Patent number: 10197562
    Abstract: The present invention provides an immunoassay leading to the rapid and simultaneous detection of antibodies to a wide range of infectious pathogens in biological fluids of infected patients. This immunoassay involves the covalent and oriented coupling of fusion proteins comprising an AGT enzyme and a viral antigen on an identifiable solid support (e.g. fluorescent microspheres). The thus obtained antigen-coupled microspheres show enhanced capture of specific antibodies as compared to antigen-coupled microspheres produced by standard amine coupling procedures.

  • Patent number: 9889968
    Abstract: A cup/lid combination includes a sleeve disposed about an exterior surface of an open-top container for movement relative to the container. A first magnet is disposed adjacent to the open top for movement relative to the container. A link assembly coupled to the sleeve and to the first magnet causes the movement of the sleeve and the movement of the first magnet to be in opposing directions. A drinking lid disposed on the open top has a gravity-controlled closure element and a second magnet coupled to the closure element. The first and second magnets are positioned for magnetic interaction to thereby fix a position of the closure element when the sleeve is only subject to the force of gravity. The first and second magnets are positioned for no magnetic interaction when the movement of the sleeve opposes the force of gravity.

  • Patent number: 9863857
    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.
