The goal of the research is to push the lateral resolution of vibrational spectroscopy. The main tool for related projects is so-called tip-enhanced Raman scattering (TERS). In particular, we are using plasmonic nanoparticles with specific optical properties at the very end of a sharp tip. With such a probe, a lateral resolution well below the Abbe limit can be achieved. Furthermore, the limits of detection reach single molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels. Research interests include:
