Optical spectroscopy of nanostructures

We combine different methods from DNA nanotechnology, optical spectroscopy and scanning probe microscopy in order to study physico-chemical processes in nanoscale materials and at the single-molecule level. In this context we create DNA origami nanostructures to detect single molecules both for biosensing and for fundamental physicochemical studies. Moreover, we use surface-enhanced Raman scattering (SERS) to study the conversion of visible light energy into chemical energy using plasmonic nanoparticles.
