Abstract

Wound healing is a complex physiological process, demanding advanced strategies for efficient tissue regeneration. To address this, we developed a novel nanofibrous matrix composed of polygalacturonic acid (PGA), polyvinyl alcohol (PVA), capsaicin, and zinc-doped mesoporous silica (Zn/MCM-41). This copolymeric matrix offers enhanced mechanical stability, controlled drug release, and improved cellular adhesion and proliferation, leading to effective tissue regeneration. Infusing capsaicin/Zn-MCM-41 confers synergistic advantages, including accelerated wound closure, diminished inflammation, and enhanced tissue regeneration, culminating in superior wound healing outcomes. Comprehensive physicochemical characterization of the nanofiber was conducted, employing techniques such as EDS, EDX, XRD, FESEM, HRTEM, FTIR, BET, TGA, DSC and Zeta potential, confirming the successful synthesis of Zn/MCM-41 at the nanoscale, exhibiting uniform porosity, colloidal stability, and thermal resilience. In vivo quantitative assessment demonstrates a significant acceleration in wound healing facilitated by the composite nanofibers. Furthermore, the incorporation of capsaicin into Zn/MCM-41 augments the wound healing process, as corroborated by histological evaluations. In summary, our investigation introduces an advanced composite nanofiber formulation that promotes accelerated wound healing quantitatively through the synergistic amalgamation of PVA, PGA, capsaicin, and Zn/MCM-41. The demonstrated efficacy of the nanofibers underscores their potential in translational regenerative medicine and wound healing applications.
