We utilize the diversity and functionality of hybrid nanocomposite materials for the development of novel devices, especially in the field of sensor technology.

Nanocomposites unite the unique properties of nanoscale materials with the great diversity of organic compounds. They feature enormous configurability and allow for the combination of diverse properties and functionalities of their constituents, as well as the exploitation of arising collective effects. Due to their charge transport characteristics and their tunable interactions with light and chemical compounds, nanocomposites exhibit great potential for utilization in innovative optoelectronic components and sensors. Here, the use of colloidal solutions for device production further enables cost- and energy-efficient, ink-based manufacturing processes.

Our group’s research focus is on the integration of nanocomposites into devices, particularly in the field of sensor technology. Hereby, new transduction principles are explored and new device types are developed. Current research activities aim at the development of selective, chromatographic sensors for volatile organic compounds (VOCs) which utilize the mass transport properties of nanocomposites, and the development of energy-efficient photo-activated gas sensors.
