Measuring device using biological cells or chemical biologically active substances contained in an analyte
First Claim
1. A measuring device (1) for measuring the presence of at least one component (3) contained in an analyte (2), said device comprising a plurality of sensors including at least one reference sensor and at least one electrical sensor (4) each having a measurement output connectable to an evaluating device, wherein the electrical sensor (4) and the reference sensor each have an electrical measurement structure (6) located on a common substrate (5), the measurement structure (6) of the electrical sensor is connected to at least one function-specific plant or animal receptor cell (7) serving as a biological sensor, wherein each electrical sensor measures the analyte (2) under investigation by measuring a morphologic or physiologic property of the receptor cell (7), wherein provided between the receptor cell and the measurement structure (6) is a structured, biocompatible micro porous interlayer (13) to which the receptor cell at least partially adheres, the measurement structure of the reference sensor being free of connections to function-specific receptor cells (7), the reference sensor and the at least one electrical sensor being arranged on the common substrate (5) to form a sensor array (22), whereby a change of the property is indicative of the presence of the component in the analyte.

Abstract
A measuring device (1) for measuring or investigating physiological parameters using biological cells or chemical and biologically active substances contained in an analyte (2). The measuring device comprises a sensor (4) with an electronic measurement structure (6) located on a substrate (5). Function-specific receptor cells and/or target cells (7) form part of the sensor (4) and are in direct contact with the measurement structure (6). For measurement, the medium under investigation can be brought into contact with the target cells or receptor cells (7). The measuring device (1) is especially compact in its design and facilitates largely feedback-free investigation of biological or chemical components contained in the analyte.
