Speaker: Prof. dr. Katrin Kneipp
Affiliation: Department of Physics, Technical University of Denmark
Title: Raman Spectroscopy using the Help of Plasmonics
Date: 24-05-2012

Host: Antoine van Oijen


Raman scattering is the inelastic scattering of photons on the vibrational quantum states of matter. The extremely weak process can be enhanced by up to 14 orders of magnitude when the scattering takes place in the enhanced and highly confined local optical fields of plasmonic nanostructures.

This effect called surface enhanced Raman scattering (SERS) turns the very weak Raman effect into a single molecule and nanoscale spectroscopic probe with exciting applications reaching from nanosciences to biomedical sensing.

The talk

  • introduces the physics behind plasmonic supported Raman scattering using one- and two-photon excitations
  • shows that SERS allows us to push spectroscopy to new limits in detection sensitivity, molecular structural selectivity and local resolution
  • discusses some exciting applications in the biomedical field
