Abstract

Among the many different types of wound dressings, nanofiber-based materials produced through electrospinning are claimed to be ideal because of their advantageous intrinsic properties and the feasibility of employing several strategies to load bioactive compounds into their structure. Bioactive compounds with antimicrobial properties have been incorporated into different wound dressings to promote healing as well as prevent and treat bacterial infections. Among these, natural products, such as medicinal plant extracts and essential oils (EOs), have proven particularly attractive thanks to their nontoxic nature, minor side effects, desirable bioactive properties, and favorable effects on the healing process. To this end, the present review provides an exhaustive and up-to-date revision of the most prominent medicinal plant extracts and EOs with antimicrobial properties that have been incorporated into nanofiber-based wound dressings. The most common methods used for incorporating bioactive compounds into electrospun nanofibers include: pre-electrospinning (blend, encapsulation, coaxial, and emulsion electrospinning), post-electrospinning (physical adsorption, chemical immobilization, and layer-by-layer assembly), and nanoparticle loading. Furthermore, a general overview of the benefits of EOs and medicinal plant extracts is presented, describing their intrinsic properties and biotechniques for their incorporation into wound dressings. Finally, the current challenges and safety issues that need to be adequately clarified and addressed are discussed.

具有抗菌功能的电纺伤口敷料：对植物提取物和精油掺入的深入研究。

在众多不同类型的伤口敷料中，通过电纺丝技术生产的纳米纤维材料被认为是最理想的材料，因为它们具有优越的内在特性，而且可以采用多种策略将生物活性化合物添加到其结构中。具有抗菌特性的生物活性化合物已被添加到不同的伤口敷料中，以促进伤口愈合，预防和治疗细菌感染。其中，药用植物提取物和精油（EOs）等天然产品因其无毒性、副作用小、理想的生物活性特性以及对愈合过程的有利影响，已被证明特别具有吸引力。为此，本综述对已纳入纳米纤维伤口敷料的具有抗菌特性的最著名药用植物提取物和 EO 进行了详尽的最新修订。将生物活性化合物加入电纺纳米纤维的最常用方法包括：电纺前（混合、封装、同轴和乳液电纺）、电纺后（物理吸附、化学固定和逐层组装）和纳米粒子负载。此外，还概述了环氧乙烷和药用植物提取物的益处，介绍了它们的内在特性以及将其融入伤口敷料的生物技术。最后，还讨论了当前需要充分澄清和解决的挑战和安全问题。

期刊介绍： Biotechnological techniques, from fermentation to genetic manipulation, have become increasingly relevant to the food and beverage, fuel production, chemical and pharmaceutical, and waste management industries. Consequently, academic as well as industrial institutions need to keep abreast of the concepts, data, and methodologies evolved by continuing research. This journal provides a forum of critical evaluation of recent and current publications and, periodically, for state-of-the-art reports from various geographic areas around the world. Contributing authors are recognized experts in their fields, and each article is reviewed by an objective expert to ensure accuracy and objectivity of the presentation.
