The research of the group „Fiber Spectroscopic Sensing” focuses on the development of miniaturized, fiber- and cavity-based Raman sensors and their interdisciplinary application in environmental, pharmaceutical and biomedical areas.
The team exploits the high chemical selectivity of Raman spectroscopy for the identification and quantification of biogenic gases, drugs and biomolecules in complex samples. The development of novel micro-structured hollow-core fibers (e.g. for guidance in the deep-UV) and optical cavities provides high signal enhancements. Thus, monitoring minimal sample concentrations onsite in small sample volumes with high selectivity and sensitivity is achieved.
The research regarding tailor-made optical sensors is closely connected to the interdisciplinary application in various environmental and life science topics. This interdisciplinary research is done in close cooperation with partners from CRC AquaDiva and the university hospital.
