  • Sensor using long range surface plasmon resonance with diffraction double-grating
    Patent number: 5846843
    Abstract: A long range surface plasmon resonance sensor for use in biological, biochemical or chemical testing. The sensor includes a first dielectric medium and a second dielectric medium having an index of refraction approximately matching the first dielectric medium. A double-grating structure is located between the first dielectric medium and the second dielectric medium. A beam of electromagnetic radiation is introduced into the second dielectric medium in a manner which causes long range surface plasmon resonance to occur such that the beam of radiation suffers attenuated total reflection. The characteristics of the resonance dependent upon the reaction between the bonding layer and the targeted bonding molecule are then detected.
