“…Various chemical methods have been used to synthesize sulfur nanoparticles. Among the most commonly used methods are aqueous surfactant assisted acid catalyzed precipitation, liquid phase chemical precipitation and water-in-oil microemulsion route [19,20]. These methods have disadvantages such as temperature dependency, large amount of surfactant requirement and being highly time-consuming [21].…”

Microbial wound infections leading to secondary complications in wound healing has resulted in high demand for therapeutic drugs with improved efficacy. Despite achieving enhanced bio-activity and higher bioavailability compared to its bulk form, nano-sulfur (SNP) has been explored to a very limited extent for wound healing applications. In this work, we prepare biogenic SNP (SNP-B) via simple biogenic technique using pomegranate (Punica granatum) peel extract and demonstrate its antimicrobial and wound healing activity. The SNP-B was characterized using powder x-ray diffractometer, FESEM, transmission electron microscopy and Raman spectroscopy. Different wound models (excision, incision, dead space and burn) were used to assess the wound healing potential of SNP-B. The 2% (w/w) SNP-B treated group exhibited enhanced wound contraction rate (excision wound, 99.62 ± 0.59%; burn wound, 99.46 ± 0.59%), breaking strength (393.2 ± 10.87 g cm−2), and granulation tissue weight (166.8 ± 9.45 mg) compared to the control group (excision wound, 84.24 ± 2.78%; burn wound, 90.58 ± 3.2%; breaking strength, 241.3 ± 16.11 g cm−2; granulation tissue weight, 91.17 ± 7.28 mg). The efficacy of 2% (w/w) SNP-B was comparable to that of standard (5% w/w povidone-iodine ointment) in all the wound models analyzed. The SNP-B showed enhanced antibacterial activity with a MIC value of 90, 80, 80, and 60 μg ml−1 for Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis and Staphylococcus aureus, respectively. The results obtained prove the potential of SNP-B as a multifunctional therapeutic agent for topical applications.
