Patent ID: 8450104

Claim:
An apparatus for optical detection of binding of at least one material component to a substance located on a surface of or inside a sensor layer due to a biological, chemical or physical interaction, which comprises: a sensor layer; a source of light, which irradiates the sensor layer, of wavelengths that include at least operating wavelengths, for which the sensor layer is transparent, at least, partially; a detector, which is placed on the pathway of the light reflected from the sensor layer or transmitted through the sensor layer, for measuring the light intensity of operational wavelengths in the spectrum of the received light; a block of result generation to generate information about the binding being detected on the basis of changes of the said spectrum, whose input is connected to the output of the detector, wherein: the thickness of the sensor layer is more than 10 micrometers and exceeds the maximal operating wavelength by at least one order of magnitude, the detector is a matrix spectrometer.
