Summary: This research aimed to extract sodium alginate from brown algae Macrocystis pyrifera and Lessonia trabeculata, and produce composite films composed of sodium alginate/ kappa-carrageenan/ iota-carrageenan, which were loaded with aminoethoxyvinylglycine. The extracted sodium alginate had low molecular weight and the composite films showed desirable drug release properties. Therefore, sodium alginate can be used to prepare composite films as an alternative to synthetic polymers for drug loading and release.

Summary: The adsorption characteristics of palladium from chloride aqueous solution onto the silica alginate (SA-Si) nanomaterial have been studied. The experiment showed that the pseudo-first-order model provided the best fitting for the adsorption of palladium ions, with an equilibrium time of 90.0 min. The Langmuir isotherm model was able to describe the adsorption isotherm result well, with a maximum adsorption capacity of 12.50 mg/g for Pd(II) on the SA-Si nanomaterial. Thermodynamic results indicated that the sorption of Pd(II) onto the SA-Si nanomaterial was endothermic and spontaneous. Additionally, the SA-Si nanomaterial showed effective adsorption for Pd(II) from various metal ions present in fission products.

Summary: This study aimed to construct block-shaped cell culture meat by using edible scaffolds as a platform for animal stem cell expansion. The tea polyphenols (TP)-coated 3D scaffolds, composed of sodium alginate (SA) and gelatin (Gel), showed good biocompatibility and mechanical support. Rabbit skeletal muscle myoblasts exhibited good adhesion and extension behavior on the TP-coated scaffolds with high expression of myogenic differentiation proteins and genes. The scaffolds with TP coating significantly improved cell proliferation rate and morphology, indicating their high potential for cultured meat production.

Summary: In this study, a three-dimensional printed porous multilayer scaffold made of cold-water fish skin gelatin was developed for osteoarticular cartilage regeneration. The scaffold mimics the structure of native cartilage, allowing chondrocytes to adhere, proliferate, and communicate, as well as transport nutrients and prevent further joint damage. Moreover, the gelatin scaffolds were found to be nonimmunogenic, nontoxic, and biodegradable. Implanting the scaffold into rat cartilage defects resulted in satisfactory repair outcomes in an animal model. Therefore, cold-water fish skin gelatin scaffolds have promising applications in regenerative medicine.

Summary: Water-soluble biopolymers gelatin and sodium alginate modified with a deep eutectic solvent were investigated as potential alternative binders for lithium-ion battery anodes. The modified binders showed improved plasticity and adhesion compared to unmodified binders and commonly used PVDF or CMC/SBR binders. Both modified gelatin and sodium alginate binders can disperse in water and be rapidly delaminated with mild ultrasound. Microscopy imaging revealed different dispersion behaviors of the two binders around graphite particles.

Summary: The marine polysaccharide fucoidan (FUC) shows great potential in pharmaceutical research for developing drug delivery systems with modified release and targeted delivery. The presence of a sulfate group in FUC makes it suitable for forming interpolyelectrolyte complexes (PECs) with various polycations. However, the structural diversity of FUC poses challenges in designing FUC-based nanoformulations.

Summary: New composite films were prepared by incorporating bacterial cellulose nanofibers and cerium oxide nanoparticles into chitosan matrices. The amount of nanofillers affected the structure and properties of the composites, including film stiffness and strength. Increasing the concentration of nanoceria improved the biocompatibility and adhesion of the films to mesenchymal stem cells. These nanocomposite films exhibit favorable properties for use as matrix materials in cell culture and wound dressings.

Summary: The development of cryogels containing metronidazole (MET) based on carrageenan (CRG) and partially deacetylated chitin nanowhiskers (CNWs) has shown promise for improved vaginal delivery. The incorporation of CNWs significantly improved the strength and homogeneity of the cryogels, resulting in sustained drug release within 24 hours. The mechanism of prolonged release was related to polymer swelling and chain relaxation in the matrix, as demonstrated by the Korsmeyer-Peppas and Peppas-Sahlin models. These cryogels exhibited a prolonged antiprotozoal effect, making them potential dosage forms for the treatment of vaginal infections.

Summary: The study used in silico modelling to simulate peptides complementary to lactoferrin, specifically focusing on the bonding site between pneumococcal surface protein (PSP) and lactoferrin (LF). The proposed peptide, EEVAPQAQAKIAELENQVHRLE, was synthesized and analyzed to confirm its purity. Experimental results showed that the peptide formed a complex with LF, leading to a change in mobility. However, no binding was observed with homomyeloperoxidase and myoglobin.
