In this section, the choices of matrix compound and solvent composition appropriate for tissue IMS are reviewed. As is well known, it is very important to choose an appropriate matrix for successful imaging measurement. A practical choice of matrix depends upon the type of analyte involved. Until today, in traditional MALDI-MS, a large variety of compounds has been empirically tested for their suitability in playing the role of a matrix; today, researchers can choose from a relatively small number of established “organic chemical matrices” such as sinapic acid (SA), α-cyano-4-hydroxy-cinnamic acid (CHCA), and 2,5-dihydroxybenzoic acid (DHB), and they have proven to be useful matrices for MALDI-imaging measurement. On the other hand, in MALDI-IMS, it is still necessary to develop a new matrix because of the extremely complex chemistry on the tissue surface. We also introduce some novel organic matrices and the further use of nanoparticles as an alternative to organic matrices from recent literature.
