The research activities in the area of biosensors of the Department of Functional Materials focus on enzymatic sensors for the determination of analytes in gaseous or liquid samples. Enzymes are used with the intent to improve the selectivity of the respective sensors.
Primarily electrochemical methods are employed in order to generate an electrical out signal related to the chemical analyte concentration.
The competence of the department in the area of film technologies can also be used for biosensors. For example, electrochemical biosensors with a three-electrode configuration can be built up using screen printing.
The research focuses on the further development and improvement of biosensors: developing new applications, improving the sensor characteristics, or simplifying the sensor set-up.
Examples of applications are the determination of formaldehyde in ambient air or of ethanol in the headspace above fruit or vegetable juices.
