Polysaccharide-based natural and synthetic nanocomposites

Characterization of Hydrothermal Deposition of Copper Oxide Nanoleaves on Never-Dried Bacterial Cellulose

“…Each BC nanofiber is a collection of smaller crystalline cellulose fibers. The smaller fibers are extruded from bacterial pores, then aggregated, and bond together in the extracellular space [38,39]. The smaller fibers do not completely bond as evidenced by neutron scattering research that showed never-dried BC nanofibers are nanoporous fibers through which water can diffuse [40].…”

Materials Based on Chitosan and Polylactide: From Biodegradable Plastics to Tissue Engineering Constructions

“…Chitosan has good film-and fiber-forming properties; it is successfully used to form hydrogels of various morphologies and micro-/nano-sized particles [54,[65][66][67][68][69][70][71]. As in the case of polylactide, significant efforts are being made to regulate and improve the properties of chitosan-containing materials by combining chitosan with other components or by modifying the chemical structure [72]. In the latter case, its derivatives or copolymers are synthesized using both hydroxyl and amine groups as reaction centers [36,[73][74][75][76][77][78][79][80][81][82].…”

Chitosan-Loaded Copper and Silver Nanocomposites as Antifungal Agents for Treatment of Pathogenic Fungi in Aquatic Environment

“…Fungi in water and sediment are found in the form of biofilms, reservoirs of microbes inside water and sediment; these membranes are surrounded by polymeric materials due to an extracellular matrix that acts as a protective shelter and makes them stable enough to resist physical forces Modern strategies depend on reducing the toxic effects on human health or the environment through the production of antimicrobials based on nanomaterials because of their effectiveness at very low concentrations, making them less poisonous and eco-friendly (Graves et al, 2017). Therefore, many materials were used as stabilizing agents to maintain the effectiveness of nanometric particles for more time with high activity, such as polysaccharides and polymers and combined with nanomaterials (Bogdanova & Chvalun, 2016;Fan et al, 2021;Sidhu et al, 2022).…”
