Project description:
A measurement principle that has caught a lot of attention in recent years due to the extremely high analytical sensitivity is called surface-enhanced Raman spectroscopy (SERS). SERS is based on plasmonic surfaces such as gold nanoparticles and leads to Raman signals which are up to 1010-fold higher than in conventional Raman spectroscopy. In this project, several multifunctional nanoparticle systems are synthesized and used for diagnostic SERS-based ex-vivo and in-vitro applications.
