Sensor for taking impedance measurements of a biological or chemical agent sample and method for detecting a biological or chemical agent in the sample by means of such an agent

摘要

The purpose of this notification is to measure the impedance of a sample of a biological or chemical agent in a potentiostat system containing a reference electrode RE and a CE -counting electrode, with electrical contacts at the edge of the sensor in the form of a connection to is characterised by having n working electrodes of WEn (7),Where n? 2, and n is advantageous i n range of 2 to 256, and the reference electrode RE (3) is common to all WEn operating electrodes (7) and its part adjacent to the WEn operating electrode (7) forms a measurement segment (8) RE -CE -WEn. The notification shall also cover the detection of a biological or chemical agent in the sample by means of such a sensor.
