Fibrous by-products, including defective or double cocoons, are obtained during silk processing. These cocoons primarily contain fibroin and sericin (SS) proteins along with minor amounts of wax mineral salts. In conventional textile processes, SS is removed in the production smooth, lustrous threads, typically discarded. However, has garnered attention for its antioxidant, antibacterial, biocompatible, anticancer properties as well excellent moisture absorption, making it a promising polymer biomedical applications. Owing to functional groups (carboxyl, amino, hydroxyl), can blend crosslink other polymers, thereby improving mechanical sericin-based materials. This study explored effects different SS/polyvinyl alcohol (PVA) ratios on porous scaffolds fabricated via freeze-drying, focusing stability, water protein release phosphate-buffered saline (PBS). The scaffold morphology revealed reduced porosity higher content, while increased PVA content led material folding layering. A greater enhanced properties, thermal although decreased. results demonstrate that be tailored by optimizing SS/PVA ratio suit specific

Current investigations into the fabrication of innovative biomaterials that stimulate cartilage development result from increasing interest due to emerging bone defects. In particular, investigation for musculoskeletal therapies extensively depends on various hydroxyapatite (HA)/sodium alginate (SA) composites. Cuttlefish (CFB)-derived composite scaffolds hard tissue regeneration have been effectively illustrated in this using a hydrothermal technique. this, HA was prepared CFB source without altering its biological properties. The as-developed nanocomposites were investigated through XRD, FTIR, SEM, and EDX analyses confirm their structural, functional, morphological orientation. higher interfacial density HA/SA nanocomposites, more hardness scaffold increased with applied load. Furthermore, nanocomposite revealed remarkable antibacterial activity against bacterial strains such as E. coli S. aureus inhibition zones measured 18 mm 20 mm, respectively. results demonstrated minor decrease cell viability compared untreated culture, an observed percentage at 97.2% nanocomposites. Hence, proposed would be excellent alternative engineering applications.

New Insights into Antiviral Natural Formulations: Biopolymeric Films for the Prevention and Treatment of a Wide Gamma of Viral Infections

Viruses, Год журнала: 2025, Номер 17(2), С. 216 - 216

Опубликована: Фев. 1, 2025

Viral infections remain a major concern, as existing treatments often yield inadequate responses or lead to the development of antiviral resistance in some cases. Fucoidan extracted from Undaria pinnatifida (F) is natural sulphated polysaccharide that exhibits action. Despite its potential, biomedical application F limited due difficult administration through trans-mucosal, skin, oral ingestion. The most effective way solve these problems propose novel methods aiming ensure better contact between biopolymers and pathogens, leading their inactivation. In this work, synthesis films based on chitosan (Ch)-coupled reported, generate synergic effect both terms antioxidant capability. Biocomposites were prepared by sonochemical method. They characterized infer structural properties, functionality, possible F-Ch interactions using Zeta FTIR, XRD techniques. biocomposites showed excellent film-forming ability. also exhibited improved activity with respect Ch individually proved be non-cytotoxic. These results demonstrate, for first time, F:Ch against bovine coronavirus human viruses (adenovirus, poliovirus, herpes simplex, respiratory syncytial virus), which could applied film form prevent treat viral infections.
