Novel approach for the synthesis of Fe3O4@TiO2 core–shell microspheres and their application to the highly specific capture of phosphopeptides for MALDI-TOF MS analysis†
Abstract
A novel approach is proposed to synthesize Fe3O4@TiO2 microspheres with a well-defined core–shell structure, and the synthesized Fe3O4@TiO2 core–shell microspheres were successfully applied for the simple and fast enrichment of phosphopeptides via direct MALDI-TOF mass spectrometry analysis.
