Evaluation of decellularized caprine small intestine submucosa encapsulated with nano-formulations of cerium oxide and curcumin in the management of burn wound

The management of burn injuries presents a significant challenge in clinical settings, yet an optimal solution remains elusive. Therefore, this study aimed to develop a topical therapeutic formulation to address the complex issues hindering burn wound healing. Emphasizing the sustained presence of bioactive principles, we synthesized a bioactive gel derived from decellularized caprine small intestine submucosa (D-CIS) and encapsulated it with nano-formulations of cerium oxide and curcumin to create a burn wound dressing material with enhanced properties. The choice of encapsulated components was guided by their antimicrobial, antioxidant, and immune-modulating characteristics, along with their inherent ability to gradually release bioactive substances. The encapsulated (cerium oxide and curcumin) D-CIS bioactive gel demonstrated a range of properties, including antimicrobial, antioxidant, and anti-inflammatory effects, along with sustained release kinetics of bioactive molecules. These combined effects facilitated accelerated burn wound healing by mitigating oxidative stress, reducing inflammation, and promoting cell recruitment for epithelial and vascular regeneration. This study contributes to the development of a novel bioactive gel incorporating cerium oxide and curcumin, offering a promising approach to enhance burn wound healing.
