Background: The aim of the present study was to investigate the potential of Nanochelating-based copper to accelerate the wound healing process and prevent infection in burn wounds.

Methods: Six to eight-week- old female BALB/c mice were burned with a 1 cm² heated copper plate on the left flank and then divided into four treatment groups, treated with C8 (nanochelating-based CuNPs), cold cream (supplementary materials) as a control drug, Silver Sulfadiazine and no treatment, respectively. Skin tissue samples were taken from the mice on days 0, 3, 8, 15 and 24. One piece was fixed in 10% neutral buffered formalin for pathological examination and the others were stored at -80°C until used for pro-inflammatory and growth factor gene expression.

Results: The healing process in the group treated with 10 mg/ml C8 was significantly faster, and the survival rate of the mice in this group was significantly higher than in the other groups. The pro-inflammatory genes were expressed and down-regulated earlier in the C8 treated mice. Histopathology confirmed the higher cure rate in the group treated with 10 mg/ml C8 compared to other control groups.

Conclusion: C8 has beneficial effects on the healing of burn wounds and the effective dose of this compound should be further investigated. The present study demonstrates the anti-inflammatory properties of nano-chelate-based copper particles' on mouse skin burns. This research opens up new possibilities in dermatology and burn therapy and highlights the potential of copper-based formulations in the treatment of burn injuries.
