  "id": "MLC-T-CHM-012080",
  "term": "Tip enhanced raman spectroscopy",
  "field": "Chemistry",
  "definitions": [
    "A surface analysis technique that combines scanning probe microscopy with Raman spectroscopy to obtain chemical information with high spatial resolution. A sharp metallic or metal-coated tip is brought close to the sample surface and illuminated by a laser, creating a highly localized enhancement of the electromagnetic field at the tip's apex. This technique achieves spatial resolution on the order of 10 to 20 nanometers.",
    "A surface analysis method that provides chemical information with nanoscale spatial resolution by using a sharp, metallized probe tip. The tip, integrated into a scanning probe microscope, creates a localized surface plasmon resonance that greatly amplifies the Raman scattering signal from the sample area directly beneath it. This technique achieves a spatial resolution on the order of 10 to 20 nanometers, far below the optical diffraction limit."
