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.

Target for MALDI imaging with two conductive-surface microscope slides. Sample preparation is a critical step in imaging spectroscopy. Scientists take thin tissue slices mounted on conductive microscope slides and apply a suitable MALDI matrix to the tissue, either manually or automatically.
Utility for proteomics designed to support the preprocessing and analysis of MALDI-TOF mass spectrometry data that loads data from mzML, mzXML and CSV files. It allows users to apply baseline correction, normalization, smoothing, peak detection and peak matching.

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.
