Welcome to the Raman & SEM Group

Our principal aim is to extend applicability of the Raman Microscpectroscopy (RM) and Scanning Electron Microscopy (SEM) for environmental analytical chemistry.

The research fields and competences of our group are

Nondestructive 2D & 3D-chemical analysis by Raman Microscpectroscopy, Surface-enhanced Raman Scattering (SERS) and Stable Isotope Raman Microspectroscopy (SIRM)

• Study of chemical composition and structure of biofilm matrices (including microorganisms, extracellular polymeric substances and inorganic compounds)
• Investigation of pollutants accumulation on the level of single bacteria by combination of RM and SERS with the stable isotope technique (e.g. ¹³C, D, ¹⁵N)
• Identification and quantification of plastic (and pigment) particles in the (sub)micro- and nano-range
• Detection and characterization of (biobased) magnetic nanoparticles / nanocomposites
• Composition, structure and reactivity of soot and atmospheric aerosols.
