Scientific Profile

The focus of the work lies on exploiting the potential of plasmonic effects on molecular and chemically synthesized metallic hybrid nanostructures for biophotonics, from basic scientific investigations to the development of bioanalytical and lab-on-a-chip systems.  

Passive plasmonics focuses on localized surface plasmon resonance (LSPR)-based sensors on metallic nanoparticles, which are used in various sensor concepts (also as microarrays) as optical signal converters. In active plasmonics, plasmon nano-antennas are used for (bio)material processing and plasmon catalysis. By combining plasmonic effects with microfluidics and image-based readout, new fields of application for molecular plasmonics are opened up. 

Possible applications include medical diagnostics, food and water analysis, and environmental technology.
