    Abstract: The invention relates to a nucleic acid-oligomer, modified by the chemical bond of a thermostable, photoinducible redoxactive unit. Said modified nucleic acid-oligomer can be used in a method for electrochemically detecting sequence-specific nucleic acid-oligomer hybridisation events. The modified nucleic acid-oligomer is bound to a conductive surface at one end and bears the thermostable, photoinducible redoxactive unit at the other free end. One part of the single-strand oligonucleotides is hybridised by treatment with the oligonucleotide solution (target) being analysed, which results in an increase in the electrical communication between the conductive surface and the thermostable, photoinducible redoxactive unit, said communication being initially non- or barely existent. This enables a hybridisation event to be detected using electrochemical methods such as voltammetry, amperometry or conductance measurement.

    Abstract: Analytische Testsysteme und Analyseverfahren, bei denen zur qualitativen und quantitativen Bestimmung von Analyten in einer Probe molekulare Schalter benutzt werden, sind durch eine an den Analyten angepasste Wahl des molekularen Schalters breit einsetzbar. Der molekulare Schalter besteht aus einer Sonde, bevorzugt eine Nukleinsäure oder ein Nukleinsäurederivat, die an eine katalytische Komponente, bevorzugt ein Enzym, gekoppelt ist. Der Analyt bewirkt eine Konformationsänderung der Sonde, wodurch der Zugang zur katalytischen Komponente für ein in der Probe befindliches Substrat verändert und die Änderung des Substratumsatzes, entspricht der Änderung der katalytischen Aktivität, gemessen wird.

    Abstract: This present invention relates methods for detecting the presence of nucleic acids in a sample. In these methods, neutral capture probes are exposed to a sample possibly containing complementary nucleic acid targets. The foregoing mixture is submitted to conditions that provide for the nucleic acid targets to bind with the neutral probes thereby generating hybrids. These hybrids are submitted to positively charged reporters such as atoms, molecules or macromolecules, which electrostatically bind to the hybrids. The complexes formed between reporters and hybrids are detected by a variety of detection methods. Kits for detecting the presence of nucleic acids in a sample are also disclosed herein.

    Abstract: This invention includes methods for identifying nucleic acids in a sample of nucleic acids by observing sequence sets present in the nucleic acids of the sample and then identifying those sequences in a nucleic acid sequence database having the sequence sets observed. In a preferred embodiment, a sequence set consists of two primary subsequences and an additional subsequence having determined mutual relationships. The methods include those for observing the sequence sets and those for performing sequence database searches. This invention also includes devices for recognizing in parallel the additional subsequences in a sample of as well as methods for the use of these devices. In a preferred embodiment, the devices include probes bound to a planar surface that recognize additional subsequence by hybridization, and the methods of use include features to improve the specificity and reproducibility of this hybridization.
