20100330699 | APPARATUS AND METHOD FOR THE DETECTION OF LIQUIDS OR SUBSTANCES FROM LIQUIDS, AND USE OF SAID APPARATUS - The embodiments relate to an apparatus and a method for detecting liquids or substances from liquids in spatially separate reaction zones. The embodiments further relate to the use of the apparatus in a plug-in module or a chip card which can be used for rapid immunological tests, for example, with the help of a reading device. The liquids or substances from liquids are detected by means of a sensor array which includes at least two sensors 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 can be 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 the pressure is applied to and compresses the diaphragm. In the sealed reaction chambers, reactions can take place independently of reactions in adjacent reaction chamber. Reaction products or substances in the liquid can be measured with smaller measurement errors in sealed reaction chamber than when the liquid flows across the entire diaphragm. | 12-30-2010 |
