The Chemical and Optical Sensing Division develops chemical and biochemical sensors and rapid tests. It focuses on the sensitive, selective detection of organic, inorganic, and biochemical species, including hazardous substances. We combine fundamental and application-oriented knowledge to develop smart detection strategies.

Our chemical sensors are based on micro-/nanoparticles and thin films that are specifically functionalized with indicators, biochemical or polymeric recognition elements targeting the analyte in question. Our instrumental development aim at miniaturisation, method coupling and multiplexing and includes methods such as microfluidics and lateral flow assays for sample handling as well as optical and electrochemical methods (fluorescence and Raman spectroscopy, electrochemiluminescence) for detection.

The development of chemical detection strategies is accompanied by theoretical modelling. For the implementation of our sensor chemistry, we pursue simple approaches such as test strips or microfluidic chips.
