Summary: In this study, chitosan oligosaccharide (COS) was used to dye and functionally modify wool fabrics with antibacterial activity via Maillard reaction. The reaction between COS and wool keratin was demonstrated using SDS-PAGE and IR analysis, confirming the formation of new keratin-COS conjugates with higher molecular weight. The color strength (K/S) of the dyed wool fabrics affected by maillard browning was greatly influenced by the reaction time, pH, and temperature. The affinity of COS to the wool could be significantly improved by pretreating the fabrics with different agents (H2O2, mercaptoethanol or protease), resulting in increased color depth of the dyed fabric. Additionally, the dyed fabrics exhibited promising antibacterial capacity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), along with good color fastness.

Summary: Hydrogels consisting of radiation-degraded chitosan, poly(vinyl alcohol), and Ag nano-filler were synthesized using two-stage and single-stage procedures. The study found that hydrogels synthesized using the single-stage procedure exhibited stronger antibacterial activity, possibly due to the higher mobility of radiation-modified chitosan in the network.

Summary: In this study, the Maillard-type glycated collagen was produced by incubating lyophilized tilapia scale collagen with alginate oligosaccharide or glucose. The results showed that glucose led to a faster increase in conjugated sugar content and a greater decrease in available lysine compared to alginate oligosaccharide during glycation. The enhanced antioxidant activity of digested collagen was found to be associated with the products of the Maillard reaction. Furthermore, alginate oligosaccharide was shown to be an excellent reducing sugar that enhances the health benefits of collagen without excessive loss of lysine, addressing a nutritional concern in Maillard-type glycation.

Summary: In this study, a bilayered asymmetric nanofibrous membrane was prepared, with a hydrophilic chitosan/chitosan oligosaccharide (COS) nanofibrous membrane as the bottom layer and a hydrophobic polycaprolactone (PCL) nanofibrous membrane as the top layer. Results showed that incorporating COS improved the wettability of the CS membrane and increased the antibacterial effects against Escherichia coli and Staphylococcus aureus. The PCL layer prevented water and bacteria adhesion. This wettable membrane has the potential to serve as a new antibacterial dressing for wound healing.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
