A Study of Scarless Wound Healing Through Programmed Inflammation, Proliferation, and Maturation Using a Redox Balancing Nanogel

The study investigates the effectiveness of a redox balancing chitosan gel with citrate-capped Mn3O4 nanoparticles for scarless wound healing. The nanogel was tested on a preclinical mice model, demonstrating its role in various stages of wound healing, including hemostasis, inflammation, and proliferation, ultimately leading to complete maturation without scarring. The in vitro characterization showed the nanogel's pH-regulated redox buffering capacity, while in vivo studies on Swiss albino mice highlighted the involvement of signaling molecules such as IL-12, IFN-γ, and α-SMA. The research underscores the importance of redox buffering in the wound healing process, with detailed histopathological investigations and angiogenesis supporting these findings.
