Surface plasmon

{
  "id": "MLC-T-CHM-011656",
  "term": "Surface plasmon",
  "field": "Chemistry",
  "definition": "A collective oscillation of free electrons at the interface between a metal and a dielectric material. These oscillations are quantized as surface plasmons and can be excited by incident light, leading to strong electromagnetic field enhancements at the surface. Surface plasmon resonance (SPR) is a common technique for detecting molecular binding events.",
