Abstract:
Die Erfindung betrifft einen Flüssigkeitsbehälter, umfassend einen Boden und Seitenwände zum Halten einer Flüssigkeit, wobei der Boden umfasst: eine ebene Sensoroberfläche, die bei Befüllung mit der Flüssigkeit in Kontakt steht; eine Lichteintrittsfläche unterhalb der Sensoroberfläche, die geeignet ist, Licht auf die Sensoroberfläche zu fokussieren; eine Lichtaustrittsfläche; und eine Mantelfläche, die geeignet ist, Licht von der Sensoroberfläche zu reflektieren, so dass es durch die Lichtaustrittsfläche austreten kann. Weiterhin betrifft die Erfindung ein Verfahren zur qualitativen oder quantitativen Analytbestimmung in einem derartigen Flüssigkeitsbehälter wobei Anregungslicht über die Lichteintrittsfläche auf die Sensoroberfläche fokussiert wird, hierdurch ein den Analyten kennzeichnender Lumineszenzmarker angeregt wird, und dann die so entstehende Lumineszenz an der Manteloberfläche reflektiert und nach Austritt durch die Lichtaustrittsfläche detektiert wird. Die Erfindung betrifft auch eine Analysevorrichtung, umfassend eine Halterung für einen Flüssigkeitsbehälter; eine Lichtquelle, die derart angeordnet ist, dass ihr Licht über die Lichteintrittsfläche auf die Sensoroberfläche des Flüssigkeitsbehälters fokussiert werden kann; sowie einen Detektor, der derart angeordnet ist, dass er das aus der Lichtaustrittsfläche des Flüssigkeitsbehälters austretende Licht detektieren kann.
Abstract:
The invention concerns a process and a device for preparing molecules. Generally, the preparation of molecules is subject to statistical variations in the number of molecules to be prepared. According to the invention, this problem is overcome in that the molecules to be prepared are applied with a high degree of dilution to a surface such that their number can be determined precisely and they can be handled in a specific manner.
Abstract:
The invention relates to a liquid receptacle (22) comprising a bottom (1) and sidewalls for holding a liquid. The bottom (1) encompasses a flat sensor surface (3) that is in contact with the liquid when the receptacle is filled, a light-incident area (2) that is located below the sensor surface (3) and is suitable for focusing light (13) onto the sensor surface (3), a light emergence area (5), and a cover area (4) that is suitable for reflecting light from the sensor surface (3) such that the light can emerge through the light emergence area (5). The invention further relates to a method for qualitatively or quantitatively determining an analyte in such a liquid receptacle (22). In said method, excitation light (13) is focused onto the sensor surface (3) via the light-incident area (2) such that a luminescent marker which characterizes the analyte is excited, and the generated luminescence is then reflected onto the cover surface (4) and is detected after emerging through the light emergence area (5). The invention also relates to an analysis device comprising a holder for a liquid receptacle, a light source (10) that is disposed such that the light (13) thereof can be focused onto the sensor surface (3) of the liquid receptacle (22) via the light-incident area (2), and a detector (17) which is arranged in such a way as to be able to detect the light (9) emerging from the light emergence area (5) of the liquid receptacle (22).

Abstract:
A composition for coating comprising at least one compound of formula (I): R a Si(R 1 ) n (X 1 ) 3-n , and optionally at least one compound of formula (II): R b Si(R 2 ) m (X 2 ) 3-m , wherein R a is a straight-chain or branched C (1-24) alkyl group, R b is an aromatic group, such as an optionally substituted carbocyclic and heterocyclic group comprising five-, six- or ten-membered ring systems, which is linked by a single covalent bond or a spacer unit, such as a straight-chain or branched alkyl residue having 1 to 8 carbon atoms, to the Si- atom, R 1 and R 2 are independently of each other a lower alkyl group, such as a straight chain and branched hydrocarbon radical having 1 to 6 carbon atoms, X 1 and X 2 are independently of each other a hydrolysable group, such as a halogen or an alkoxy group and n, m are independently of each other 0 or 1, with the proviso that if n and m are independently of each other 0 or 1, X may represent the same or different groups.
Abstract:
A process is disclosed that uses the Langmuir-Blodgett technique to produce ultra-thin monolayers that contain receptor or biological molecules. Cross-linkable, non-amphiphilic matrix molecules are used, with which receptor and/or biological molecules are intercalated or covalently coupled. A new process, a modified Lemieux reaction, is disclosed for that purpose.
Abstract:
The invention relates to a method for screening target-ligand interactions while using a chemical library of ligands, to the chemical library of ligands as such, to a method for producing the chemical library, as well as to the use of the chemical library for developing active agents and for developing molecular sensors. The screening method comprises the following steps: (a) measuring at least one fluorescence property of a locally addressable chemical library of ligands that is immobilized on a solid phase, whereby a molecular fluorescence sensor is bound to each ligand; (b) adding the target, and; (c) measuring the same fluorescence property/properties of the chemical library as described in step (a). The locally addressable chemical library of ligands that is immobilized on a solid phase is characterized in that each ligand is bound to a molecular fluorescence sensor in a preferable manner in which the molecular fluorescence sensor is bound between the ligand and the solid phase and/or to the end of the ligand situated opposite the solid phase.
Abstract:
A pneumatic vehicle tire comprises a carcass (11) extending between two bead cores (15). A belt structure (18) is provided between the carcass (11) and a tread strip (19) which is connected with a pair of sidewalls (20). A runflat reinforcement (17) is arranged at the inner side of each sidewall (20). A reinforcer (13) is arranged within each bead portion of the tire. A bead filler (14) extends from the bead ring (15) along the reinforcer (13). To improve the runflat performance, handling and comfort properties of such a runflat tire the reinforcer (13) is arranged at the inner side of the bead filler (14). The reinforcer (13) comprises metal cords. The bead filler (14) which extends beyond an end (13a) of the reinforcer (13) is made of a soft rubber compound with an IHRD hardness lower than (80), e.g. between (75) and (79).
