Special Issue Information

Dear Colleagues,

Polysaccharides represent an essential and diverse class of biomolecules. Their remarkable properties and potential applications have attracted significant research interest across multiple disciplines. From the complex processes involved in their synthesis to the diverse ways in which they are utilized in different sectors, there is a wealth of knowledge and innovation to be shared. This Special Issue encourages submissions that cover all aspects related to the synthesis of polysaccharides, including innovative methods, mechanisms, and advancements. We also welcome contributions that explore the diverse applications of polysaccharides in various fields. The scope of contributions includes, but is not limited to, the following:

  • Novel synthetic approaches and technological explorations regarding polysaccharides;
  • Structural analysis and characteristic studies on polysaccharides from different sources;
  • Mechanisms and regulations in the synthesis process of polysaccharides;
  • Applications of polysaccharides in the biomedical field, such as drug delivery or tissue engineering;
  • Applications and innovations in polysaccharides in the food industry;
  • The potential of polysaccharides in environmental protection and sustainable development;
  • Emerging applications and prospects for polysaccharides in other fields.

We look forward to receiving submissions of research papers and review articles demonstrating innovation, high quality, depth, and breadth.

Novel self-assembled aggregates of stearic acid (SA)-modified burdock polysaccharide (BP) for loading lutein were constructed, and the release and absorption properties of lutein in the aggregates in simulated gastrointestinal fluid were investigated. Three different degrees of substitution (DS) of SA-BPs were used to embed lutein, resulting in the encapsulation efficiency exceeding 90%. The aggregates were uniformly spherical, with a particle size range of 227–341 nm. XRD analysis revealed that lutein was present in a non-crystalline state within the aggregates. FT-IR and FS analysis demonstrated that lutein was located in the hydrophobic domains of SA-BP. The highest bioavailability of lutein in these aggregates reached 4.36 times that in the unmodified samples. These aggregates were able to remain stable in gastric juice and enhance the release rate of lutein in intestinal fluid. The transport of lutein-loaded SA-BP aggregates in Caco-2 cells competed with P-glycoprotein inhibitors, mainly promoting the transmembrane absorption of lutein through caveolae (or lipid raft)-related and clathrin-dependent endocytosis pathways. The above results suggest that SA-BP aggregates have the potential to be promising carriers for the efficient delivery of hydrophobic lutein. Full article
