Summary: A novel and green strategy based on polysaccharides electrodeposition was explored to synthesize silver nanoparticles (AgNPs) with adjustable particle sizes and their polysaccharide-based nanocomposite films. The polysaccharides acted as the electrodeposited material, as well as the reducing and stabilizing agents for the synthesis of AgNPs. The as-fabricated AgNPs from four different polysaccharides had different particle sizes ranging from 2.19 to 12.89 nm, which were determined by the reducibility and stabilizing ability of the polysaccharides. This research provides a facile and controllable electrodeposition strategy for green synthesis of AgNPs with different sizes and their nanocomposite films.

Summary: In this study, films containing silver nanoparticles (AgNPs) were synthesized using green techniques. The inclusion of AgNPs improved the mechanical and barrier properties of the films. The migration of AgNPs from the films to different food simulants was studied, revealing a complex mechanism. The release of silver from the films was higher for films prepared with in situ AgNPs compared to those with AgNP L. Biodegradation tests showed that the films achieved significant weight loss after 90 days, without releasing phytotoxic compounds into the soil.

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.
