Desorption ionization on silicon

{
  "id": "MLC-T-CHM-003071",
  "term": "Desorption ionization on silicon",
  "field": "Chemistry",
  "definition": "A soft ionization technique in mass spectrometry that uses a porous silicon surface to facilitate the desorption and ionization of analytes. The sample is deposited onto the silicon, and a laser pulse or electric field then desorbs and ionizes the molecules. This method is particularly effective for analyzing small molecules and peptides directly from surfaces.",
