  • SPR sensor plate and immune reaction measuring instrument using the same
    Patent number: 6507402
    Abstract: To provide an SPR sensor plate which allows easy fixation of an antibody and easy retention of a subject and which can be manufactured easily, as well as an immune reaction measuring instrument employing this SPR sensor plate. The SPR sensor plate includes: a plate-shaped light waveguide 3 that allows light from a light source 21 to be transmitted therethrough; and a sensing metal film 5 formed on part of a surface of the light waveguide 3. A reflecting metal film 7 is formed on opposite end surfaces of the light waveguide 3 except for a light incident surface 9 and a light exit surface 11 forming inclined surfaces having a same inclination.
    Type: Grant
    Filed: July 6, 2001
    Date of Patent: January 14, 2003
    Assignee: Suzuki Motor Corporation
    Inventors: Mitsuhiro Negami, Muneaki Nakamura
  • SPR sensor cell and immunoassay apparatus using the same
    Patent number: 6432364
    Abstract: An SPR (surface plasmon resonance) sensor cell comprising: a light-transparent core; a clad covering the core and having a through hole at a predetermined position to communicate with the core; and a predetermined thin metal film formed on an exposed surface of the core corresponding to the through hole.

  • Immunoassay apparatus
    Patent number: 6139797
    Abstract: An immunoassay apparatus comprising: at least two optical fibers, each having a first end serving as an SPR sensor; a light source for emitting a predetermined light to a second end of said optical fibers; a spectrometer for analyzing a wavelength distribution of a reflected light reflected by the SPR sensors; a main control block for controlling operation of the light source and the spectrometer; and an apparatus main body for containing the aforementioned components.
