Plasmonics



24h15

Teaching purpose


Introduce the plasmons of surface, the located plasmons. Describe the behavior of the light in the interfaces or in an aqueous environment in the presence of metallic nanoparticles. Application to the biosensors.

Programme


  • SPR
  • Sensors with evanescent wave
  • Introduction on interferometric sensors (1/2h)
  • History. Experiment of Otto. Experiment of Kretschmann-Raether
  • Multilayers. Metallic nanoparticles. Evanescent waves, interferences and resonances
  • SPR and molecules. Optical biosensors conception
  • Plasmonics biochips: kinetics and imaging


Application


  • TP / project (20 hours) on the experiments of Otto, Kretschmann-Raether
  • Optical answer of colloidal metallic nanoparticles
  • Molecular interactions without marker by SPRi.
