Abstract: A diffractometric sensing device for analyzing molecular interactions is described, the diffractometric sensing device comprising a transparent carrier medium, the carrier medium comprising a grating structure (42.1-42.5) with a plurality of consecutive surfaces or lines and a plurality of binding sites arranged thereon, the binding sites being configured to interact with one or more target molecules, wherein the grating structure is configured to diffract a portion of coherent light propagating in the carrier medium so as to produce a constructive interference signal at a light detector (4.1-4.4), the signal being dependent on molecular interactions at or in the vicinity of the binding sites. The invention offers more sensitivity, faster response, miniaturization, easy manufacturing and more applications compared to current diffractometric sensing devices.
