Preparation of a TiO2-NH2 modified MALDI plate for on-plate simultaneous enrichment of phosphopeptides and glycopeptides

In this work, a TiO2 film was prepared on a MALDI plate by atomic layer deposition (ALD) technique and then modified with -NH2 to obtain a TiO2-NH2 modified plate for on-plate simultaneous enrichment of phosphopeptides and glycopeptides.238
