Visualizing vinca alkaloids in the petal of Catharanthus roseus using functionalized titanium oxide nanowire substrate for surface‐assisted laser desorption/ionization imaging mass spectrometry

SUMMARY Imaging mass spectrometry (IMS) is a powerful technique that enables analysis of various molecular species at a high spatial resolution with low detection limits. In contrast to the matrix‐assisted laser desorption/ionization mass spectrometry (MALDI‐MS) approach, surface‐assisted laser deso...
