MALDI-TOF mass spectrometry is a versatile analytical technique to detect and characterize mixtures of organic molecules. In microbiology, it is used as a rapid, accurate, and cost-effective method for identifying microorganisms (bacteria, fungi, and viruses).

2023年4月29日 · Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI – TOF MS) is an emerging potential tool used for the identification and diagnosis of microorganisms.

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]

Matrix Assisted Laser Desorption/Ionization (MALDI) is used to analyze extremely large molecules. This technique directly ionizes and vaporizes the analyte from the condensed phase. MALDI is often used for the analysis of synthetic and natural polymers, proteins, and peptides.

2023年8月8日 · Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry, commonly abbreviated as MALDI-TOF MS, is a powerful analytical technique used in the field of mass spectrometry.

Matrix assisted laser desorption ionization (MALDI) is one technique and has become a powerful tool for the analysis of peptides and proteins since its introduction by Karas and Tanaka. This technique combines an energy absorbing compound (matrix) with the analyte of interest.
