Surface Plasmon Resonance (SPR)

25.2K
Surface plasmon resonance (SPR) is the underlying optical phenomenon behind label-free biosensors to evaluate the molecular affinity, kinetics, specificity, and concentration of biomolecules. In SPR, biomolecular interactions occur on a biosensor made of a thin layer of metal on a prism. Real-time interactions of biomolecules can be monitored by measuring the changes of light reflected off the underside of the metal.
This video describes the basic concepts of SPR and how it is used to analyze...

Area of Science:

  • Nanophotonics
  • Surface Science
  • Spectroscopy

Background:

  • Thin conductive surfaces are crucial for tip-enhanced spectroscopy.
  • Tip-enhanced spectroscopy utilizes localized surface plasmon resonance for nanoscale field enhancement.
  • Gap-mode tip-enhanced spectroscopy enhances fields further with a tip-substrate junction.

Purpose of the Study:

  • To investigate a heterometallic platform for enhanced tip-substrate interactions.
  • To explore plasmon-mediated nanoscale reactions at a gold tip-silver nanoplate junction.
  • To assess the potential for controlled ablation and patterning.

Main Methods:

  • Utilized a gold atomic force microscope tip and a silver nanoplate substrate.
  • Irradiated the heterometallic junction to excite plasmon resonances.
  • Observed nanoscale reactions and material ablation under laser illumination.

Main Results:

  • A plasmon-mediated reaction was triggered at the tip-substrate junction.
  • Hot electron transfer from the gold tip to the silver nanoplate was observed.
  • The nanoscale reaction caused ablation of the thin silver nanoplate, even at low laser intensities.

Conclusions:

  • The heterometallic platform enables efficient nanoscale electromagnetic field enhancement.
  • The enhanced fields drive plasmon-mediated reactions leading to material ablation.
  • This approach shows promise for nanoscale patterning and photoinduced chemical reactions on metal surfaces.
