Abstract: Methods are provided for producing an array of immobilized nucleic acids on an array device. The array device has a plurality of microlocations each having an electrode. At least one of the microlocations has a synthetic addressing unit coupled to the microlocation. The microlocation is the activated, usually by electronically biasing the electrode of the microlocation. The at least one microlocation is then contacted by a conjugate which has a nucleic acid and a synthetic binding unit. The conjugate is then coupled to the microlocation through an interaction between the synthetic binding unit and the synthetic addressing unit. In one embodiment, the synthetic binding unit and synthetic addressing unit may be pRNA, pDNA, or CNA.

Abstract: The present invention relates to conjugates of synthetic binding units and nucleic acids. The present invention also relates to methods for sorting and immobilizing nucleic acids on support materials using such conjugates by specific molecular addressing of the nucleic acids mediated by the synthetic binding systems. Particularly, the present invention also relates to novel methods of utilizing conjugates of synthetic binding units and nucleic acids to in active electronic array systems to produce novel array constructs from the conjugates, and the use of such constructs in various nucleic acid assay formats. In addition, the present invention relates to various novel forms of such conjugates, improved methods of making solid phase synthesized conjugates, and improved methods of conjugating pre-synthesized synthetic binding units and nucleic acids.

Abstract: The invention relates to a novel method for the production of CNA oligomers and to artificial supramolecular CNA-p-RNA pairing systems and to the use thereof, especially in biotechnological assays.

Abstract: The invention relates to a method for simultaneously detecting mutations in different nucleotide sequences and for determining the transcription rate of mutated and non-mutated nucleotide sequences. The inventive method comprises the following steps: hybridizing single-stranded sample nucleotide sequences to single-stranded reference nucleotide sequences, fixating, before or during hybridization, single-stranded reference nucleotide sequences or single-stranded sample nucleotide sequences, or fixating, after or during hybridization, heteroduplices from reference and sample nucleotide sequences on an electronically addressable surface, incubating them with a substrate that recognizes heteroduplex mismatches, and detecting the substrate bonds.
