Introduction: Electrochemical sensors and sensor systems

This research area covers the development of knowledge and expertise of the electrode-liquid interface and its application in electrochemical micro-and nanodevices. The three basic detection principles are studied: potentiometry, amperometry and conductometry. Besides developing electrochemical sensors, the integration into lab-on-a-chip systems is implemented using cleanroom microfabrication. This opens up new operational principles such as redox cycling and the use of ultra-micro electrodes. In addition, integration of electrochemical cells in a Lab-on-a-chip enables the conversion of electro-active species.

Application of these electrochemical sensors and systems are in the field of health care, life sciences as well as in the field of environment and sustainability.
