Summary: Cross-linking of cellulose nanocrystals/chitosan composite films using glutaraldehyde as the cross-linking agent through conventional heating and microwave curing was found to enhance water resistance properties and reduce water vapor permeability. The addition of CNC significantly decreased WVP, swelling, and solubility of chitosan films, especially for microwave-cured GA-cross-linked CNC/chitosan films. Biodegradation testing showed that cross-linked chitosan composite films had lower degradability rates compared to uncross-linked composites, particularly microwave-cured CNC/chitosan films, with identified degrading microorganisms of Ophiocordyceps heteropoda, Enterobacter kobei, and E. roggenkampii.

Summary: In this study, starch/powdered activated carbon composite films were prepared by incorporating different amounts of PAC into a starch matrix using the solvent casting method. The mechanical properties of the biopolymer film were examined, and it was found that the barrier properties decreased with the increase in filler content. The results did not show a monotonic dependence of the mechanical parameters on PAC content, except for the maximum strain, which decreased with increasing additive amount.

Summary: In this study, nano-SiO2 was incorporated into polyvinyl alcohol/xylan matrix to prepare an inorganic-organic hybrid composite film with improved mechanical and barrier performance. Adding 1% nano-SiO2 increased the contact angle of the composite film from 89.6 degrees to 110.4 degrees, increased the tensile strength from 11.2 to 14.8 MPa, and decreased the oxygen permeability from 1.83 to 0.27 (cm3·µm)/(m2·d·kPa), corresponding to a 23% increase in contact angle, 32% increase in tensile strength, and 85% decrease in oxygen permeability. These results suggest that the nano-SiO2 modified xylan film has great potential as a barrier film in food packaging.

Summary: In this study, chitosan films were improved by incorporating nanofillers to enhance their mechanical properties, barriers, and antibacterial properties. The addition of lignin nanoparticles improved UV blocking property, while the inclusion of acylated soy protein isolate nanogel enhanced the sustained antibacterial property. The optimal composite film showed increased tensile strength and decreased oxygen barrier property compared to pure chitosan film, exhibiting higher antibacterial activity. However, the incorporation of nanofillers slightly reduced light transmission and increased surface roughness of the films.

Summary: Biodegradable films based on chitosan, glycerol, and defatted Chlorella biomass were prepared and characterized, showing that increasing the content of defatted algal biomass improved mechanical properties but reduced water barrier and optical properties of the films. Through microscopy and spectroscopy analysis, the enhancement in properties was attributed to the uniform distribution of DCB and the establishment of hydrogen bond interactions between components.

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.
