Preventing infections is one of the main focuses of wound care. The colonisation of wounds by microorganisms can in fact have negative consequences on the healing process, delaying it. Here, we propose the use of essential oils as natural antimicrobial agents for cellulose-based fibrous dressings. We demonstrate the production of composite electrospun fibres that effectively encapsulate three different types of essential oils (cinnamon, lemongrass and peppermint). The fibrous scaffolds are able to inhibit the growth of Escherichia coli, even when small amounts of essential oils were used. At the same time, they are not cytotoxic, as proved by biocompatibility assays on skin cell models. The created dressings are promising as advanced biomedical devices for topical treatments.
预防感染是伤口护理的主要重点之一。事实上,微生物在伤口处的定植会对愈合过程产生负面影响,延缓愈合。在此,我们提议将精油用作基于纤维素的纤维敷料的天然抗菌剂。我们展示了复合电纺纤维的制备,这种纤维能有效包裹三种不同类型的精油(肉桂、柠檬草和薄荷)。即使使用少量精油,这种纤维支架也能够抑制大肠杆菌的生长。同时,皮肤细胞模型的生物相容性试验证明,它们没有细胞毒性。所制备的敷料作为用于局部治疗的先进生物医学装置具有广阔前景。
