摘要:On the GO: Graphene (G) and graphene oxide (GO) supported on silica are demonstrated to be excellent adsorbents for reversed-phase and normal-phase solid-phase extraction (RP- and NP-SPE) towards various analytes ranging from small molecules to proteins and peptides. Notably, G-bound silica is capable of extracting proteins with large molecular weight and phosphorylated peptides, making it particularly suitable for MALDI-TOF mass spectrometry.
