Polysaccharide-based biopolymeric magnetic hydrogels for remediation of antibiotics from aqueous solution.

Polysaccharide-based biopolymeric magnetic hydrogels have garnered significant attention as effective materials for wastewater treatment due to their high adsorption capacity and environmentally friendly nature. This review examines recent advancements in the development of biopolymeric magnetic hydrogels derived from polysaccharides such as cellulose, chitosan, alginate, carrageenan, starch, and gums, with a focus on their application in removing antibiotics from contaminated water as it not only enhances adsorption performance but also simplifies separation processes after treatment, making them highly efficient for practical applications. The review aims to provide a comprehensive overview of the synthesis techniques, performance characteristics, and interaction mechanisms of these hydrogels, highlighting their renewability and suitability for large-scale water treatment.

Preparation and Characterization of Photo-Cross-Linkable Methacrylated Silk Fibroin and Methacrylated Hyaluronic Acid Composite Hydrogels.

Composite biomaterials with excellent biocompatibility and biodegradability are crucial in tissue engineering. In this work, a composite protein and polysaccharide photo-cross-linkable hydrogel was prepared using silk fibroin methacrylate (SFMA) and hyaluronic acid methacrylate (HAMA). SFMA was obtained by the methacrylation of degummed SF with glycidyl methacrylate (GMA), while HA was methacrylated by 2-aminoethyl methacrylate hydrochloride (AEMA).

Development of Composite Sponge Scaffolds Based on Carrageenan (CRG) and Cerium Oxide Nanoparticles (CeO NPs) for Hemostatic Applications.

In this study, a novel absorbable hemostatic agent was developed using carrageenan (CRG) as a natural polymer and cerium oxide nanoparticles (CeO NPs). CRG-CeO-0.5 and CRG-CeO-1 composites were prepared by compositing CeO to CRG + CeO at a weight ratio of 0.

Versatile Potential of Photo-Cross-Linkable Silk Fibroin: Roadmap from Chemical Processing Toward Regenerative Medicine and Biofabrication Applications.

Over the past two decades, hydrogels have come to the forefront of tissue engineering and regenerative medicine due to their biocompatibility, tunable degradation and low immunogenicity. Due to their porosity and polymeric network built up, it is possible to incorporate inside drugs, bioactive molecules, or other biochemically active monomers. Among biopolymers used for the fabrication of functional hydrogels, silk fibroin (SF) has received considerable research attention owing to its known biocompatibility and tunable range of mechanical properties.

Antimicrobial and Antibiofilm Properties of Latvian Honey against Causative Agents of Wound Infections.

Honey is widely used in traditional medicine and modern wound healing biomaterial research as a broad-spectrum antimicrobial, anti-inflammatory and antioxidant agent. The study's objectives were to evaluate the antibacterial activity and polyphenolic profiles of 40 monofloral honey samples collected from beekeepers in the territory of Latvia. The antimicrobial and antifungal activity of Latvian honey samples were compared with commercial Manuka honey and the honey analogue sugar solutions-carbohydrate mixture and tested against , , , clinical isolates produced , and .
