Abstract: The invention relates to improved molecular-biological processing equipment and an improved method of processing biological samples. The invention combines the provision of biologically functional molecules such as nucleic acids and peptides and of derivatives or analogs of these two classes of molecules in miniaturized flow cells with the sequential addition of reagents or fluids and serves for the processing of biological samples, such as proteins, nucleic acids, biogenic small molecules such as e.g. metabolites, viruses or cells, which for this purpose are introduced into the miniaturized flow cells.

Abstract: The invention relates to a method for producing polymers, in particular synthetic nucleic acid double strands of optional sequence, comprising the steps: (a) provision of a support having a surface area which contains a plurality of individual reaction areas, (b) location-resolved synthesis of nucleic acid fragments having in each case different base sequences in several of the individual reaction areas, and (c) detachment of the nucleic acid fragments from individual reaction areas.

Abstract: The invention relates to a template-based method for preparing nucleic acid double strands.

Abstract: A method for producing a support for determining analytes. The method comprises the steps of (a) providing a support comprising at least one channel, comprising a conduit having an intake and an outlet for passing fluid from the intake to the outlet, in the support body, (b) passing liquid with building blocks for synthesizing polymeric receptors through the channel or channels of the support body, (c) site- and/or time-specifically immobilizing the receptor building blocks in each case on predetermined positions in the channel or channels by illumination and (d) repeating steps (b) and (c) until the required receptors have been synthesized in each case on the predetermined positions.

Abstract: The invention relates to a method for the determination of analytes using carrier chips comprising arrays of different receptors in immobilized form on the surface of said chips. The method is performed dynamically in several cycles. Information obtained in a previous cycle on the modification or alteration of said receptors is used in the following cycle.

Abstract: The invention relates to a method of increasing the sensitivity and specificity of nucleic acid chip hybridization tests and to devices suitable for carrying out the inventive method.

Abstract: The invention relates to an extraction method for isolating target molecules from a sample using a microfluidic carrier.

Abstract: The invention relates to a method and an apparatus for determining analytes by electronic detection using a microfluidic support.
