The research and development project ”SNIFF” is a cooperation of scientists from the Application Center for Plasma and Photonics of the Fraunhofer Institute for Surface Engineering and Thin Films IST, the University of Applied Sciences and Arts (HAWK), the Technical University Clausthal, and the Fraunhofer Heinrich Hertz Institute HHI. The final objective of the consortium is the development of absolutely new methods to analyze the widely used and hazardous solvent formaldehyde. Formaldehyde, which is carcinogenic in the case of permanent exposure or high doses, can currently only be detected and analyzed by demanding processes. A novel optical sensor technology is intended to facilitate the mobile analysis and permanent monitoring of formaldehyde concentrations in the air in a simple way. For the manufacture of the new glass fiber sensors, laser-based processing techniques, plasma processes for surface functionalization and chemometric analysis methods are used.
