  • Devices and Methods for Detection of Biomolecular Interactions
    Publication number: 20120122235
    Abstract: Devices, systems, and methods are provided for the detection of biomolecular interactions. The interactions between one or more target DNA strands, one or more receptor DNA strands, and one or more probe DNA strands, if necessary, are used to detect the one or more target DNA strands. The one or more target DNA strands or the one or more probe DNA strands may be coupled to a magnetic bead, and the one or more receptor strands may be coupled to the Hall device.

  • Biomolecular-based actuator
    Patent number: 7014823
    Abstract: This invention relates to actuators having biologically-based components, and methods of making and using the same. The actuator of the invention has a movable member that moves substantially linearly as a result of a biomolecular interaction of biologically-based components within the actuator. These actuators can be utilized in nanoscale mechanical devices to, e.g., pump fluids, open and close valves, and provide translational movement.

  • Detection of magnetic domains by tunnel junctions
    Patent number: 3972035
    Abstract: Tunnel junctions are used to detect magnetic domains, such as bubble domains, using the change in Fermi level of one (or both) electrodes due to the magnetic field of the domain. The Fermi level shift causes the tunnel barrier height to change, leading to a change in tunneling conductance which is detectable as a current or voltage change. A simple tunnel junction in flux coupling proximity to the magnetic domains is suitable, but more sensitive detectors are made using Schottky barrier junctions, and magnetic semiconductors which exhibit conduction band splitting due to the stray field of the domains. In another embodiment, the magnetic sheet supporting the domains provides the tunnel barrier for sensing of the domains within it. Detection of submicron domains is easily achieved.
