Abstract: The present invention relates to arrays of biochemical and/or biofunctional elements such as nucleic acids (oligonucleotides, for example) or other biomolecules on a carrier surface and methods of producing such arrays using photoactivation of predetermined areas for synthesis using an illumination matrix that is computer-controlled to generate an exposure pattern. This exposure pattern can be adjusted and monitored by computer using a light sensor matrix, for example a CCD matrix, to allow precise, controlled illumination of specific regions and therefore attachment of array building blocks to those specific regions. The methods and compositions of the invention permit spatially resolved photochemical synthesis of polymer probes on a carrier.

Abstract: A method for preparing receptor-coated particles is described which comprises the following steps: a) providing a support body, b) conducting a liquid containing particles into or onto the support body, c) immobilizing the particles on at least one surface area of the support body, d) conducting a liquid which contains receptors or receptor building blocks for synthesizing polymeric receptors over the immobilized particles, e) coupling the receptors or receptor building blocks location—or/and time-specifically to the immobilized particles at in each case predetermined positions of the support body, f) repeating, where appropriate, the steps (d) and (e), until the desired receptors have been synthesized on the immobilized particles at the in each case predetermined positions of the support body.

Abstract: In the case of a method for producing a fluid device with a fluid structure having an active height, a basic wafer is provided, which comprises a supporting substrate, an insulating layer on the supporting substrate and a patterned layer on the supporting substrate, the thickness of the patterned layer determining the active height of the fluid structure. Following this, the fluid structure is produced in the patterned layer of the basic wafer, said fluid structure extending through the semiconductor layer. A transparent wafer is then applied so that the fluid structure is covered. Subsequently, the supporting substrate and the insulating layer are removed from the back so that the fluid structure is exposed at a second surface of the patterned layer. Finally, a second transparent wafer is attached to the exposed second surface of the semiconductor layer so that the fluid structure is covered. The essential parameter of the fluid device, viz.
