The term matrix-assisted laser desorption ionization (MALDI) was coined in 1985 by Franz Hillenkamp, Michael Karas and their colleagues. [3] These researchers found that the amino acid alanine could be ionized more easily if it was mixed with the amino acid tryptophan and irradiated with a pulsed 266 nm laser.

ASCENT Proprietary: ASCENT is an LC and GC-MS data analysis automation tool, provided as SaaS over a cloud platform.
The original MALDESI design was implemented using common organic matrices, similar to those used in MALDI, along with a UV laser. The current MALDESI source employs endogenous water or a thin layer of exogenously deposited ice as the energy-absorbing matrix where O-H symmetric and asymmetric stretching bonds are resonantly excited by a mid-IR ...

MALDI mass spectrometry imaging (MALDI-MSI) is the use of matrix-assisted laser desorption ionization as a mass spectrometry imaging [2] technique in which the sample, often a thin tissue section, is moved in two dimensions while the mass spectrum is recorded. [3]
It is a variation of matrix-assisted laser desorption/ionization (MALDI). [ 1 ] [ 2 ] In MALDI, the sample is mixed with a matrix material and applied to a metal plate before irradiation by a laser, [ 3 ] whereas in SELDI, proteins of interest in a sample become bound to a surface before MS analysis.
