Breakthrough in Wound Healing: Novel Sodium Alginate Emulsion Gel Shows Promising Results

Researchers from the Isfahan University of Technology in Iran have developed a novel sodium alginate emulsion gel that demonstrates excellent wound healing properties. The gel, cross-linked through hemiacetal and ionic interactions using dialdehyde carboxymethyl cellulose (DCMC) and CaCO, encapsulates curcumin (CU) in a tunable, interconnected porous network controlled by DCMC concentration. In vivo results showed a significant acceleration in wound closure, with an 85.0 ± 5.12 % reduction by day 12, compared to 18.97 ± 5.43 % in the control group. Histopathological analysis revealed reduced inflammation, attributed to the emulsion gel's antioxidant and antibacterial properties.
