A one- or two-dimensional arrangement of flow cells is provided, as part of an array of sample compartments, with at least one inlet and outlet for each sample compartment, formed by a base plate and a body, with an arrangement of spatial recesses corresponding to the (geometrical) arrangement of the sample compartments, combined with the base plate. The arrangement allows for supplying to or removing from the sample compartments, which can be arranged at a high quantity on a small base area, even very small amounts of samples or reagents. An arrangement of one or more sample compartments includes a base plate and a body combined with the base plate in such a way that one or more recesses for generation of one or more flow cells fluidically sealed against one another, each with at least one inlet and one outlet, are formed between the base plate and the body, wherein at least one outlet of each flow cell is joined with a reservoir fluidically connected with the flow cell, the reservoir being operable to receive liquid exiting the flow cell, besides methods for its manufacturing and their use.

Flow cell array and the utilization thereof for multianalyte determination

A device includes a planar optical waveguide, as part of a sensor platform, and, connected to the platform directly or by means of a sealing medium, a sealing layer. The sealing layer forms either directly or by means of a sealing medium a tightly sealing layer. The sealing layer includes a multitude of recesses at least open towards the sensor platform, which form a corresponding multitude of sample compartments in a 2-dimensional arrangement. Each of the sample compartments has different biological or biochemical recognition elements, for the specific recognition and binding of different analytes, immobilized in five or more discrete measurement areas, wherein the measurement areas are in optical interaction with excitation light emanating from the optical waveguide, as part of the sensor platform which forms a demarcation of the sample compartments, and wherein the sample compartments are operable to be cleared from received sample or reagent solutions and to then receive, optionally without washing steps, further sample or reagent solutions, which are supplied to the same sample compartments.
