  • Tapered tubular optical waveguide probe for magnetic focusing immunosensors
    Patent number: 6858440
    Abstract: A waveguide probe for the detection of pathogens in a sample which comprises a laser, a first and a second tubes that converge at a point to form a proximal end. A magnet is positioned in the end to configure to focus paramagnetic microspheres attached to antigen/antibody/optically labeled antibody complexes in the field of view. The proximal end is polished to form an aperture.
    Type: Grant
    Filed: November 1, 2002
    Date of Patent: February 22, 2005
    Assignee: The Board of Governors for Higher Education, State of Rhode Island and Providence Plantations
