Special Issue Information

Dear Colleagues,

This Special Issue continues the exploration of recent research advances in the polysaccharides and carbohydrate polymers, following the success of the first volume of the Special Issue, which published six regular papers. Further details can be found below:

Natural polymeric materials (NPMs) perfectly fit the increasingly common trend of green and sustainable chemistry. Within this group, biopolymers based on carbohydrates, particularly polysaccharides, should be distinguished, since they are readily available at low costs, making them one of the main building blocks of plants. Therefore, growing interest in research on the preparation, modification, and potential application of NMPs as structural components and carriers of active substances (e.g., in pharmaceutic and cosmetic products or functional foods), as well as in separation processes, biotechnology, and energy storage, may be observed. This indicates that NPMs may constitute an alternative to the currently used synthetic polymers, and this field of research carries enormous potential, both in the area of basic research and application.

Accordingly, this Special Issue is devoted to the most recent high-quality original research papers or comprehensive reviews covering all aspects of the synthesis, structural modification, characterization, and application of carbohydrate/polysaccharide-based natural polymeric materials.

Ferulic acid (FA) is a bioactive compound known for its potent antioxidant and anti-inflammatory properties; however, its poor water solubility significantly limits its bioavailability and therapeutic potential. In this study, a solid dispersion of FA (FA-SD) was developed using Eudragit® EPO via the solvent evaporation method, achieving a 24-fold increase in solubility (42.7 mg/mL) at a 1:3 drug-to-polymer ratio. Expandable gastroretentive films were subsequently formulated using starches from Hom-Nil rice, glutinous rice, and white rice, combined with chitosan as the primary film-forming agents, via the solvent casting technique. Hydroxypropyl methylcellulose (HPMC) K100 LV was incorporated as an adjuvant to achieve controlled release. At optimal concentrations (3% w/w starch, 2% w/w chitosan, and 2% w/w HPMC), the films exhibited favorable mechanical properties, swelling capacity, and unfolding behavior. Sustained release of FA over 8 h was achieved in formulations containing HPMC with either Hom-Nil or glutinous rice starch. Among the tested formulations (R6, G6, and H6), those incorporating Hom-Nil rice starch demonstrated the most significant antioxidant (10.38 ± 0.23 μg/mL) and anti-inflammatory (9.26 ± 0.14 μg/mL) effects in murine macrophage cell line (RAW 264.7), surpassing the activities of both free FA and FA-SD. These results highlight the potential of anthocyanin-rich pigmented rice starch-based expandable films as effective gastroretentive systems for enhanced FA delivery. Full article

Electrospun alginate nanofibers are emerging as versatile materials for biomedical, environmental, and packaging applications due to their biocompatibility, biodegradability, and functional tunability. However, the direct electrospinning of alginate remains a significant challenge, mainly due to its polyelectrolytic nature, rigid chain structure, and limited chain entanglement. This review provides a comprehensive analysis of recent strategies developed to overcome these limitations, including polymer blending, chemical modification, the addition of surfactants, multi-fluid techniques, and process optimization. We systematically discuss the integration of nanofibers with functional agents such as microorganisms, bioactive compounds, plant extracts, and nanoparticles, highlighting their potential in wound healing, active packaging, bioremediation, and controlled release systems. This review also examines the scalability of alginate electrospinning, summarizing recent patents, industrial solutions, and challenges related to the standardization of the process. Key knowledge gaps are identified, including the need for long-term stability studies, structure–function correlations, green processing approaches, and expansion into novel application domains beyond healthcare. Addressing these research directions will be crucial to unlocking the full potential of alginate nanofibers as sustainable, high-performance materials for industrial use. Full article
