Pharmaceutics, Journal Year: 2023, Volume and Issue: 15(10), P. 2514 - 2514

Published: Oct. 23, 2023

Hydrogels prepared from natural polymer have attracted extensive attention in biomedical fields such as drug delivery, wound healing, and regenerative medicine due to their good biocompatibility, degradability, flexibility. This review outlines the commonly used hydrogel preparation, including cellulose, chitosan, collagen/gelatin, alginate, hyaluronic acid, starch, guar gum, agarose, dextran. The polymeric structure process/synthesis of polymers are illustrated, polymer-based hydrogels formation properties elaborated. Subsequently, applications based on tissue regeneration, other summarized. Finally, future perspectives them discussed. For polymers, novel technologies enzymatic biological methods been developed improve structural properties, development new natural-based or derivatives with high performance is still very important challenging. hydrogels, materials, like double-network hydrogel, multifunctional composite microrobots designed meet advanced requirements applications, strategies dual-cross-linking, microfluidic chip, micropatterning, 3D/4D bioprinting explored fabricate materials for applications. Overall, increasing interest strategies/methods fabrication highly desirable

Nanocellulose Extraction from Biomass Waste: Unlocking Sustainable Pathways for Biomedical Applications

The Chemical Record, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Abstract The escalating global waste crisis necessitates innovative solutions. This study investigates the sustainable production of nanocellulose from biomass and its biomedical applications. Cellulose‐rich materials–including wood, textiles, agricultural residues, food by‐products–were systematically processed using alkaline, acid, oxidative pretreatments to enhance fiber accessibility. Mechanical techniques, such as grinding homogenization, combined with chemical methods like acid hydrolysis 2,2,6,6‐Tetramethylpiperidin‐1‐yl‐oxyl (TEMPO) oxidation, were employed successfully isolate nanocellulose. Post‐treatment modifications, including surface coating cross‐linking, further tailored properties for specific results demonstrated nanocellulose's biocompatibility, biodegradability, functional versatility. In wound healing, it enhanced moisture management exhibited antimicrobial properties. Its high area facilitated efficient drug loading controlled release in delivery Nanocellulose bioinks supported cell proliferation 3D bioprinting tissue engineering. Additional applications biosensors personal care products also identified. advances materials science, aligning resource conservation circular economy principles address sector needs.

Poly(lactic acid)/nanocellulose biocomposites for sustainable food packaging

Cellulose, Journal Year: 2024, Volume and Issue: 31(10), P. 5997 - 6042

Published: June 8, 2024

Abstract Considerable interest in food packaging research has been prompted by the rising environmental impact of waste, customer awareness for readily accessible foods with extended shelf life, and ecological consciousness about scarcity natural resources. The utilization plastic-based resulted a significant concern due to accumulation substantial quantities plastic surrounding areas. Research efforts are being motivated health considerations pursuit developing biodegradable films. Besides, poly(lactic acid) (PLA) suggested as possible substitute petroleum-based polymers because its sustainability, simple accessibility, biodegradability. PLA is made from sugar beet or maize starch that may be fermented bacteria generate material desirable qualities like transparency rigidity. However, there need further improvement certain properties PLA, such flexibility, toughness, permeability, thermal properties. One potential approach enhancing these attributes involves integration nano-reinforcement. utilisation nanocellulose derived biomass garnered recent times owing renewable nature, ability biodegrade, impressive mechanical strength, low density, considerable economic worth. In this study, we present comprehensive overview most up-to-date methods synthesising use filler manufacture nanocomposites packaging. addition, study examines emerging challenges advantages associated biocomposites incorporated sector.
