Surface-assisted laser desorption/ionization (SALDI) is a matrix-free mass spectrometry (MS) approach that utilizes the unique properties of a nanostructured surface to promote desorption and ionization. However, there are still questions on what constitutes a suitable SALDI substrate for mass spectrometric application. A range of SALDI substrates prepared by anodization with an oxidizing electrolyte was investigated. The laser desorption/ionization (LDI) performance was examined on a reflectron time-of-flight (ToF) mass spectrometer. The physicochem. properties of the substrates were characterized by a number of surface anal. techniques including SEM, at. force microscopy (AFM), secondary ion mass spectrometry (SIMS), XPS and water contact angle measurement. Examination of surface cleaning technologies and methods for surface chem. modification were carried out. Correlation between the substrate physicochem. properties and the LDI performance was determined It was found that only the substrate, which had a thick nanostructured layer, was effective for LDI-MS. SALDI substrate was found to have a high surface potential. However, this unique property offered no advantage for the application of LDI-MS. Surface chem. is also an important factor in affecting the LDI performance. Plasma etching can effectively remove the surface contamination but it also increases the thickness of the oxide layer. Fluorine and hydroxyl termination is advantageous. Fluorine passivation increases the surface hydrophobicity, which confines the analyte solution droplet to a smaller area and also withdraws the electronic d. from the surface, and acidifies the surface Si-OH moieties, which is believed a major proton source. The effect of laser etching was investigated by SIMS and XPS imaging and provided new insight of the SALDI ionization mechanism. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Synthetic Route of 92-36-4
