The Laboratory for Nano-Optics deeply regrets the tragic accident and the death of Dr. Dmitry Fedyanin. We express our sincere condolences to Dmitry's family and friends. Dmitry was a recipient of a Walter Benjamin Position of the DFG on “Pulsed electrically driven single-photon sources on diamond” and since July 2023 he has been a research associate in our group. We have been collaborating since almost a decade on the electroluminescence from color centers in diamond. We mourn the loss of a good friend and of a talented young scientist.

Nano Sensing
A major advantage of optical probes is their ability to detect low quantities of target molecules without direct contact to the sample. Although fluorescence-based approaches are available and sufficiently sensitive, they often lack the necessary flexibility for being integrated into lab-on-a-chip systems. We focus on nanophotonics-based sensing as it promises to build on the advantages of optical sensing, while overcoming its limitations by providing a high sensitivity, specificity, dynamic range, as well as the possibility for easy integration into simple and affordable devices. Furthermore, we aim at advancing single-molecule techniques with emphasis on biosensing applications.
