Abstract

This study was conducted to synthesize γ-AlOOH (bohemite)-based nanocomposites (NCs) of Au/γ-AlOOH-NC and its functionalized derivative using chitosan (Au/γ-AlOOH/Ctn-NC) and with the help of one-step Mentha piperita. The physicochemical characteristics of the NCs were investigated. In addition, biomedical properties, such as antibacterial activity under in vitro and in vivo conditions, and cell viability were assessed. Wound healing activity on infected wounds and histological parameters were assessed. The gene expressions of TNF-α, Capase 3, Bcl-2, Cyclin-D1 and FGF-2 were investigated. The TEM and FESEM images showed the sheet-like structure for bohemite in Au/γ-AlOOH-NC with Au nanoparticles in a range of 14-15 nm. The elemental analysis revealed the presence of carbon, oxygen, aluminum, and Au elements in the as-synthesized Au/γ-AlOOH. The results for toxicity showed that the produced nanocomposites did not show any cytotoxicity. Biomedical studies confirmed that Au/γ-AlOOH-NC and Au/γ-AlOOH/Ctn-NC have anti-bacterial properties and could expedite the wound healing process in infected wounds by an increase in collagen biosynthesis. The administration of ointment containing Au/γ-AlOOH-NC and Au/γ-AlOOH/Ctn-NC decreased the expressions of TNF-α, and increased the expressions of Capase 3, Bcl-2, Cyclin-D1 and FGF-2. The novelty of this study was that bohemite and Au nanoparticles can be used as a dressing to accelerate the wound healing process. In green synthesis of Au/γ-AlOOH-NC, phytochemical compounds of the plant extract are appropriate reagents for stabilization and the production of Au/γ-AlOOH-NC. Therefore, the new bohemite-based NCs can be considered as candidate for treatment of infected wounds after future clinical studies.
