Abstract
The present disclosure provides a diffraction based biosensor containing at least two diffraction gratings. The first grating is referred to as an in-coupling diffraction grating and the coherent light source (laser) is directed to illuminate the in-coupling grating, and the biosensor is configured such that a selected order of the light beam diffracted from the in-coupling diffraction grating illuminates a second biosensor grating coated with analyte-specific receptors which are selected to preferentially bind with analytes being tested for that may or may not be located in a sample being tested.
