Research in the Kneipp group combines concepts of modern developments in spectroscopy, nanotechnology, and chemistry with the overall objective of laying groundwork for sensitive optical characterization. We integrate enhancement and high lateral resolution in vibrational spectroscopic experiments with complex microstructured systems and combine different microspectroscopy and imaging approaches. Our research includes 

• surface enhanced Raman scattering of complex samples
• multimodal microspectroscopy with a focus on bioanalysis and biophysics
• basic aspects of surface enhanced hyper Raman scattering
• plasmonic catalysis
