Annotation	Two nanostructured surfaces are introduced as advantageous substrates for Desorption Electrospray Ionization Mass Spectrometry (DESI-MS). Nano-Assisted Laser Desorption/Ionization (NALDITM) plates coated with silicon nanowires (SiNWs) and Indium Tin Oxide (ITO) layers on glass are both conductive nonpolar surfaces that were originally designed as superior substrates for matrix-free Laser Desorption Ionization (LDI). In this study NALDI/SiNWs and ITO were tested as potentially useful DESI substrates for selected model analytes (cyclosporine, beauverolide, surfactin and nystatin). Both nanostructured surfaces produced more intense and longer-lasting signals than other tested surfaces (polytetrafluoroethylen (PTFE), glass, polymethylmethacrylate (PMMA) and chromatography paper)
