<p>A detection cell (2) which is used as a component of an optical biosensor comprises a transparent base plate (8) and a sample plate (4) on the base plate. The sample plate has a matrix of wells (6) extending through it to each receive a sample. The base plate includes a waveguiding film and a diffraction grating means to incouple an incident light field into the waveguiding film beneath a well to generate a diffracted light field to enable the detection of a change in the effective refractive index of the waveguiding film.</p> |
