Design and fabrication of highly hydrophilic magnetic material by anchoring l-cysteine onto chitosan for efficient enrichment of glycopeptides

Hydrophilic magnetic host–guest Ti–phenolic networks: a promising material for the highly sensitive enrichment of glycopeptides and phosphopeptides

“…TG analyses of MNPs, mTiCD, and mTiCD@AG were performed to study the thermal stability of the as-prepared adsorbents. 52 As shown in Fig. 2C, mTiCD@AG has high thermal stability up to 260 °C.…”

Selective anchoring of Pt NPs on covalent triazine-based frameworks via in situ derived bridging ligands for boosting photocatalytic hydrogen evolution

“…18,19 Glutathione and L-cysteine have been proposed as bridging ligands to selectively stabilize a Pt cocatalyst on the substrate material for efficient photocatalytic performance through the covalent/non-covalent interaction. 20,21 However, decorating the surface of COFs which are equipped with stable conjugated structures via grafting bridging ligands is always random and challenging. 22,23 The obtained COF-based catalysts with homogeneous Pt NPs still encounter lower stability due to the high surface energy of the noble metal, which induces agglomeration during a prolonged reaction.…”

Effective Enrichment of Phosphopeptides Using Magnetic Polyoxometalate-Based Metal–Organic Frameworks

“…Protein phosphorylation, as an important mechanism, is known for regulating various cellular functions as well as some diseases like Alzheimer’s disease and cancer. − Identifying and comprehensively mapping phosphorylation by mass spectrometry (MS) techniques are crucial for understanding the etiology and pathogenesis of these diseases. , However, the variability and complexity of phosphoproteins have presented many difficulties for direct MS analysis. , The enrichment strategy has become one of the bottlenecks in proteomics research.…”
