Confocal Raman microscopy combines the properties of confocal microscopy - high, spatial resolution in 3D - with the advantages of Raman spectroscopy - precise substance identification via the vibrational modes of the involved molecules.

The HOT uses confocal Raman microscopy for example to

  • non-invasively analyze living biofilms
  • non-invasively identify bacteria species
  • detection of microplastics in complex environmental samples
  • functional analysis of proteins, peptides, and amino acids

often using specific molecular resonances for signal enhancing or directly in the form of resonance Raman spectroscopy.
