摘要：

Silver iron oxide nanoparticles (AgFeO2 NPs) with narrow size distribution have been synthesized, characterized and was applied for biothiols separation. AgFeO2 and AgFeO2 modified chitosan (AgFeO2@CTSNPs) were synthesized using a hydrothermal method and then characterized by electron microscopy (transmission electron microscopy (TEM), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX)), X-ray diffraction (XRD), and Fourier transform infrared (FTIR). Different biological thiols (dithiothreitol, glutathione, thiabendazole, and sulfamethizole) were investigated and characterized using matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS) and surface assisted laser desorption/ionization mass spectrometry (SALDI-MS). The new material displays dual functionality; 1) for separation and 2) can be served as the matrices for SALDI-MS. Data showed a dear background in the case of nanomaterials compared to conventional matrices (mefenamic acid and 2,5-dihydroxybenzoic acid (DHB) for MALDI-MS). (C) 2014 Elsevier B.V.
