Abstract
Bacterial infections pose significant threats to human health, and the rising issue of antibiotic resistance necessitates exploring alternative therapeutic strategies. In this study, Ferula assa-foetida essential oil (EO) as an herbal medicine was first analyzed using gas chromatography-mass spectrometry (GC-MS). Polycaprolactone-gelatin nanofibers were then prepared via electrospinning. Biological efficacies (antioxidant and antibacterial properties) of nanofibers impregnated with the nanogel containing the EO were finally investigated. As a result, the five major identified compounds were ethyl trifluoromethyl disulfide (33.6%), β-pinene (15.1%), δ-3-carene (6.6%), dihydro-β-agarofuran (6.0%), and γ-eudesmol (5.5%). Nanogel was developed from a primary nanoemulsion, with a 55 ± 7 nm droplet size and a zeta potential of -31 ± 2 mV. Nanofibers with a hydrophobic surface (contact angle (θ) 107°) impregnated with the nanogel demonstrated remarkable antibacterial efficacy, inhibiting the growth of Escherichia coli and Staphylococcus aureus by nearly 100% and Pseudomonas aeruginosa by 90%. These findings suggest that the developed formulation has the potential to serve as an effective antibacterial wound dressing, warranting further investigation.
