Front Cover: TiO₂ Nanocoral Structures as Versatile Substrates for Surface‐Assisted Laser Desorption/Ionization Mass Spectrometry (ChemNanoMat 4/2019)

The cover image illustrates the matrix-free surface-assisted laser desorption/ionization (SALDI) of small organic molecules, gold clusters, and polyoxometalates using versatile TiO2 nanocoral (TNC) substrates. SALDI mass spectrometry (MS) is a powerful technique for rapidly analyzing a myriad of compounds including biomolecules and polymers. However, previous studies were limited to detecting natural/organic-based molecules. Biphasic TNC structures consisting of an anatase base film and a rutile nanocoral layer allow analysis of not only organic compounds and polymers but also inorganic clusters by SALDI-MS.
