Research areas

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:

  • near-field optics
  • electromagnetic and chemical interactions on the nanometer scale
  • Raman spectroscopy
  • structural investigation of proteins and protein aggregations
  • membrane-protein interaction
  • single-site catalysis

Teaching fields

Prof. Deckert is involved in the teaching of general physical chemistry and gives courses on scanning probe microscopy.

Research methods

Prof. Deckert's laboratories are dedicated to the molecular-level investigation of surface structures, in particular of biomolecules and heterogeneous catalysis using ultra-high resolution:

  • tip-enhanced Raman scattering (TERS) microscopy
  • force distance spectroscopy
