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.
