Abstract

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.
