Department of Spectroscopy/Microscopy
The investigation of physical and chemical processes has long relied on spectro-optical and imaging methods. Meanwhile, innovative concepts permit examinations of single molecules with femtosecond resolution and a spatial accuracy of a few nanometers, so that e.g. life processes can be explored in detail on the molecular or cellular level together with their dynamic changes in time. Current examples of the Department’s research include IR/THz sensors and Raman spectroscopy, the latter (i) with its expansion into what is known as CARS microscopy, (ii) with defined field (and, thus, signal) amplification by plasmonically active metal nanostructures (SERS, TERS), and (iii) its instrumental implementation in extremely miniaturized high-performance systems for spectroscopy and microscopy.
Our general aim is to overcome existing technical limits in spectroscopy and microscopy in order to evolve new methods and instrumental technologies for the materials and life sciences.
