Nano Optics

Focus

The newly established Nano Optics group focuses on advancing the knowledge of light-matter interactions below the diffraction limit of light as well as development of novel experimental methods that address current topics in biology, biophysics, and biochemistry. Although we employ a wide range of procedures, our investigative toolbox is mainly comprised of single-particle and single-molecule optical techniques. In particular, approaches such as light microscopy, laser spectroscopy, quantum optics, near-field optics, and plasmonics are combined with chemical and bioanalytical methods and biotechnologies to achieve a robust array of exciting projects.

Research projects

• ERC-CZ Optical imaging of single protein dynamics
• High-fidelity fast tracking of protein motion mechanisms
