I work at the edge of physics, chemistry and biology with a main focus on the investigation of nanoscale optical phenomena and their application to interdisciplinary issues. In particular, optical near-field effects are exploited to control the light matter interaction and are applied for super-resolution microscopy as well as for nanoscale spectroscopy. As such optical antennas formed of noble metal nanoparticles are used to address organic materials with single-molecule sensitivity and to manipulate energy transfer processes. Nanoparticle gap antennas provide high flexibility in terms of tailoring their plasmon resonances, the light confinement and electromagnetic field enhancement. Utilizing nanolensing effects of self-similar structures, e.g., nanoparticle trimer antennas, optical antennas are fabricated with advanced properties for studying luminescent materials and bio matter.

Currently, I work on the investigation of surface characteristics and structural changes in block copolymer nanoparticles by means of TERS. This project is part of the new collaborative research center 1278 “PolyTarget” established at the FSU Jena.
