Skin burn is one of the major causes of morbidity and mortality in burn patients due to its susceptibility to infection. The disruption of the epidermal barrier, combined with the denaturation of proteins and lipids, provides a fertile environment that is rich in bacterial nutrients for microbial growth, making it significantly prone to infection. This study aimed to formulate a thermoresponsive hydrogel containing silver nanoparticles (300 ppm), oligo chitosan 2%, and curcumin (0.1%) in the polymer pluronic F127 matrix with a final concentration of 13% to effectively promote the healing of skin wounds. The prepared thermoresponsive hydrogel was investigated for its physical and chemical stability, gelation temperature, and chemical composition. In addition to in vitro antibacterial activity against Staphylococcus aureus found in burn infections, in vivo burn healing and antibacterial activities were also investigated and compared with those of a commercial product using burn-induced infected wounds in mice. The formulation showed antibacterial activity with effective values for wound healing properties, as shown in vivo and by histopathological studies. This study also demonstrates that the thermoresponsive hydrogel was successful as an antibacterial and burned wound-healing transdermal drug delivery system.
