Patent ID: 7708945

Claim:
A device comprising: a sensor platform having one planar optical waveguide wherein the planar optical waveguide has a plurality of waveguide regions; a sealing layer forming, either directly or with a sealing medium, a tight seal with said planar optical waveguide; and a plurality of recesses opening at least towards said sensor platform, which form a corresponding plurality of sample compartments, said plurality of sample compartments being arranged with at least two sample compartments in a length direction and at least two sample compartments in a width direction, wherein each of said sample compartments comprises only a single waveguide region and has different biological or biochemical recognition elements for specific recognition and binding of different analytes immobilized in five or more discrete measurement areas on said planar optical waveguide, said measurement areas being arranged with at least two measurement areas in a length direction and at least two measurement areas in a width direction, said measurement areas are in optical interaction with excitation light emanating from said optical waveguide, as part of said sensor platform which forms a demarcation of said sample compartments, and said sample compartments are operable to have sample or reagent solutions received therein cleared therefrom and to have further sample or reagent solutions supplied thereto.
