Summary: This study reports the successful functionalization/magnetization of bio-polymer to produce chitosan-magnetic graphene oxide grafted polyaniline doped with cobalt oxide (ChMGOP-Co3O4). The effects of experimental factors on the uptake of As(V) ions using ChMGOP-Co3O4 were examined, and the study validates the removal process of As(V) through analysis of adsorption capacity, rate, and thermodynamic parameters. The sorbent showed high adsorption capacities and removal efficiencies, and the adsorption mechanism is predominantly physisorption. This study highlights ChMGOP-Co3O4 as an exceptional adsorbent material for efficient isolation of As(V) from aqueous media.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
