Research Summary

The workgroup of molecular spectroscopy and nanosystems at the university of Düsseldorf investigates molecules and molecular aggregates ("cluster") by laser spectroscopy. Main research field is the examination of hydrogen bridge bonded systems like water as solvent biomolecular aggregates, f.e. DNA base pairs.

Our main goal is a better understanding of the building blocks of life, such as the high ordered network structure of water, the pair formation of the DNA bases and the folding of peptides. These structures are crucially affected by bridges between a hydrogen atom and two electronegative elements.

These supramolecular structures can be investigated by laser spectroscopy. The investigations are performed at ultra low temperatures in the gas phase and in the condensed phase, mainly in water.

Other fields of investigation are scanning tunneling microscopy of laser excited biomolecular aggregates and nanoparticles and the synthesis of functional nanosystems.
