  • Monitoring of refractive index of optical sensor for determination of surface structure changes
    Patent number: 6127183
    Abstract: The invention relates to a method of analysing a chemical or physical interaction taking place in a film layer at an optical sensor surface when the film layer is contacted with a fluid sample containing a species capable of interacting with the film layer, wherein the interaction is monitored by determination of the refractive index of the film layer through a light-intensity signal producing technique by measuring the relationship between a parameter of the incident and/or reflected light and one of the minimum, the maximum and the centroid of the light intensity signal curve.
