摘要:
An array of valves are arranged in n columns and m lines and which are each designed to control a fluid flow in an associated flow channel in a lab-on-a-chip system. The array includes at least two valves, every column having not more than one valve and every line having from zero to n valves. A device is used for actuating the valves. The valves are pressure-actuated. To produce the device, the flow channels are arranged in accordance with the arrangement of the valves. Which valves are actuated being changeable by movement of projections relative to array of valves so as to change which valves the projections are pressed against.
摘要:
A system for the integrated and automated analysis of DNA or protein, including a single-use cartridge, with an analysis device having a control device, and devices for capturing and processing signals, the control device carrying out a completely automatic process and evaluation of molecular diagnostic analysis via single-use cartridges (Lab-on-a-Chip). Controlling of an analysis process, which occurs in the cartridge, involves the subsequent displacement and thermostatisation of liquids with a first device, and with a second device the signals which are obtained during the analysis are processed. The first and the second devices are synchronized in such a manner that the analysis process of the sample can be carried out in a totally integrated manner thus producing an immediate result.

摘要:
An apparatus for detecting liquids or substances from liquids in spatially separate reaction zones using a plug-in module or a chip card for rapid immunological tests, for example, with the help of a reading device. The liquids or substances from liquids are detected by a sensor array and on which at least one diaphragm is arranged. Individual sensors are spatially separated from each other on a plane by means of walls. The diaphragm is filled with liquid that is to be analyzed. Sealed reaction chambers are created when pressure is applied to the diaphragm. Pores in the diaphragm are completely closed in the zone of the walls while the pores are merely reduced in size and liquid can continue to be exchanged in zones directly above the sensors. No liquid can be exchanged between adjacent reaction chambers as long as pressure is applied to and compresses the diaphragm.

摘要:
A biochip includes a flat carrier and an array of spots containing catcher molecules which are arranged on the carrier. Each spot is associated with a microelectrode arrangement for impedance spectroscopic detection of binding events occurring between the catcher molecules and the target molecules applied via an analyte solution. In order to increase the sensitivity or the binding-specific measuring effects of the bio-chip, the electrode arrangement is at least partially embedded in a hydrophilic reaction layer containing catcher molecules and which is permeable to target molecules.
