Abstract: ABSTRACT The present invention relates to the field of biomedical engineering and advanced wound care management, focusing on the developrnent of an eco-friendly, biopolymeric nanogel for enhanced burn wound healing. The invention discloses a sustainable nanogel system synthesized using naturally derived polymers such as chitosan, alginate, gelatin, cellulose derivatives, and plant-based polysaccharides. The formulation is developed through a green synthesis approach employing environmentally benign techniques including ionic gelation, self-assembly, and enzymatic cross-linking, thereby eliminating the use of toxic chemicals and hazardous solvents. The synthesized nanogel exhibits a three-dimensional cross-linked nanoscale ., structure with high water retention and swelling capacity, enabling the maintenance of a moist wound environment conducive to rapid healing. The system allows for controlled and sustained release of incorporated bioactive agents such as antimicrobial, anti-inflammatory, antioxidant compounds, and growth-promoting factors. In certain embodiments, natural antimicrobial agents including curcumin, neem extract, aloe vera, and green-synthesized silver nanoparticles are integrated to provide broad-spectrum antimicrobial activity and reduce infection risks. The nanogel demonstrates excellent biocompatibility, biodegradability, mechanical strength, flexibility, and bioadhesiveness, ensuring effective application and retention at the wound site. Additionally, the biomimetic properties of the polymeric matrix support cellular activities such as fibroblast proliferation, collagen synthesis, angiogenesis, and re-epithelialization, thereby accelerating tissue regeneration and minimizing scar formation. The invention . further allows customization of formulation parameters to suit different types of burn wounds. Owing to its cost-effectiveness, scalability, and reliance on renewable natural ' resources, the proposed nanogel system represents a safe, sustainable, and efficient alternative to conventional wound care materials, offering significant improvements in therapeutic outcomes and patient compliance.
