Surface-assisted laser desorption/ionization

Surface-assisted laser desorption/ionization (SALDI) is a soft laser desorption technique used for analyzing biomolecules by mass spectrometry.[1][2] In its first embodiment, it used graphite matrix.[1] At present, laser desorption/ionization methods using other inorganic matrices, such as nanomaterials, are often regarded as SALDI variants. A related method named "ambient SALDI" - which is a combination of conventional SALDI with ambient mass spectrometry incorporating the DART ion source - has also been demonstrated.[3]
