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.
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.

MALDI is an ionization technique where laser energy is absorbed by a matrix to create ions from large molecules without fragmentation. The matrix, typically in excess, is mixed with the analyte molecule and deposited on a target.

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 ...
