Thus, it is important to prepare novel nanofibers for a wound dressing that can control bacterial infections. In our study, the novel self-assembled nanofibers of benzalkonium bromide with bioactive peptide materials of IKVAV and RGD were designed and fabricated.Methods: Different drug concentration effects of encapsulation efficacy, swelling ratio and strength were determined. Its release profile in simulated wound fluid and its cytotoxicity were studied in vitro. Importantly, the antibacterial efficacy, inhibition of biofilm formation effect and wound healing against MRSA infections in vitro and in vivo were performed after observing the tissue toxicity in vivo.Results: It was found that the optimized drug load (0.8%) was affected by the encapsulation efficacy, swelling ratio, and strength. In addition, the novel nanofibers with average diameter (222.0 nm) and stabile zeta potential (− 11.2 mV) have good morphology and characteristics. It has a delayed released profile in the simulated wound fluid and good biocompatibility with L929 cells and most tissues. Importantly, the nanofibers were shown to improve antibacterial efficacy, inhibit biofilm formation, and lead to accelerated wound healing following infection with methicillin-resistant Staphylococcus aureus.Conclusion: These data suggest that novel nanofibers could effectively shorten the wound-healing time by inhibiting biofilm formation, which make it promising candidates for treatment of MRSA-induced wound infections.Keywords: nanofibers, wound enclosure, methicillin-resistant Staphylococcus aureus, biofilm, antibacterial effect

Every year millions of lacerations and incisions taken place and require an effective methodology to manage the wound for a better life. The primary causes include mechanical trauma and surgical procedures. The rapid healing of the wound is critical to prevent further infection and reduction pain etc. Current options comprise of sutures, staplers, surgical strips and glues, again the intervention depends on the type of wound and the surgeon preference. The current wound closure techniques pose various potent limitations and confronting the problems to create a desired wound closure technique is necessary for faster and effective wound healing management. The surgical staplers are fast and easy to use wound closure devices, which approximates the edges of the wounds together by staples. The staples are mostly made up of metals like titanium and stainless steel. By modifying the existing stapling method using biodegradable staples that are expected to have good mechanical properties, not require removal procedure, minimized scarring and an overall acceleration in wound healing with minimal complications. Present, the paper focuses on the novel hypothesis on natural fiber reinforced biodegradable polymer staples as wound enclosures with high strength and degradability. [ABSTRACT FROM AUTHOR]
