MALDI imaging techniques dedicated to drug-distribution studies

Previously, MS was often used to analyze the composition and structure of biological molecules present in solutions. Today, technology developments enable the application of MS for the analysis of localized biomolecules on biological tissue surfaces. This technique is called MS imaging. MALDI imaging MS is a technique whereby thousands of compounds present in a tissue section are detected simultaneously without labeling. Although initially used for the detection of biomolecules such as peptides and proteins, this technology is also used today for drug detection. These characteristics make MS imaging an ideal technology that is perfectly adapted for ADME (absorption, distribution, metabolism...
