Multimodal Instrumentation

Scientific Profile

The group 'Multimodal Instrumentation' focuses on research and development of novel application-oriented optical tools, and fiber-optic probes, tailored for specific applications for basic research, medical ex-vivo and in vivo diagnostics, as well as for industrial process analysis. The research covers a range of spectroscopic, fluorescence-based, and interferometric techniques.

Furthermore, the group 'Multimodal Instrumentation' is also exploring and developing novel high-throughput Raman devices for rapid single cells and tissue analysis. This research is aiming at improving the acquisition speeds of current devices by removing the human factor from the acquisition procedure and directly applying multivariate statistical methods during the acquisition, which allows the investigation and monitor of experiments rapidly and in a time-dependent fashion.

Addressed application fields

In-vivo medical application: 

  • Development of a medical Raman platform for clinical diagnostics for the in vivo acquisition of Raman spectra. The accompanying fiber optic Raman probe can be used in combination with an endoscope with a working channel, e.g. a cystoscope.
  • Cells research (disease diagnosis, drug – cell interactions).
  • Raman-based assays
  • Pharmaceutical applications
  • Cardiac tissue characterization and localization of fibrotic streaks
