Summary: In this study, amino-functionalized monodisperse polymeric microcapsules were prepared using a microfluidic approach for efficient adsorption of heavy metal ions from aqueous solution. The presence of abundant amine groups on the shell of the microcapsules played a key role in the successful adsorption of Cu2+, Cd2+, and Zn2+ ions. The cyclic adsorption-desorption efficiency of the amino-functionalized microcapsules remained stable for five cycles, demonstrating their potential for practical applications in heavy metal ion removal.

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.
