Wound dressings produced by electrospinning exhibit a fibrous structure close to the one of the extracellular matrix of the skin. In this article, electrospinning was used to fabricate fiber mats based on the well‐known biopolymers poly(ɛ‐caprolactone) (PCL) and methylcellulose (MC) using benign solvents. The blend fiber mats were cross‐linked using Manuka honey and additionally used as a biodegradable platform to deliver bioactive glass particles. It was hypothesized that a dual therapeutic effect can be achieved by combining Manuka honey and bioactive glass. Morphological and chemical examinations confirmed the successful production of submicrometric PCL‐MC fiber mats containing Manuka honey and bioactive glass particles. The multifunctional fiber mats exhibited improved wettability and suitable mechanical properties (ultimate tensile strength of 3–5 MPa). By performing dissolution tests using simulated body fluid, the improved bioactivity of the fiber mats by the addition of bioactive glass was confirmed. Additionally, cell biology tests using human dermal fibroblasts and human keratinocytes‐like HaCaT cells showed the potential of the fabricated composite fiber mats to be used as wound dressing, specially due to the ability to support wound closure influenced by the presence of bioactive glass. Moreover, based on the results of the antibacterial tests, it is apparent that an optimization of the electrospun fiber mats is required to develop suitable wound dressing for the treatment of infected wounds.

通过结合生物活性玻璃和麦卢卡蜂蜜生产新型聚(ε-己内酯)-甲基纤维素电纺伤口敷料。

通过静电纺丝生产的伤口敷料呈现出接近皮肤细胞外基质之一的纤维结构。在本文中,静电纺丝被用于制造基于众所周知的生物聚合物聚(ε-己内酯)(PCL)和甲基纤维素(MC)的纤维垫,使用良性溶剂。混合纤维垫使用麦卢卡蜂蜜进行交联,另外还用作可生物降解的平台以提供生物活性玻璃颗粒。据推测,通过结合麦卢卡蜂蜜和生物活性玻璃可以实现双重治疗效果。形态学和化学检查证实成功生产了含有麦卢卡蜂蜜和生物活性玻璃颗粒的亚微米 PCL-MC 纤维垫。多功能纤维垫表现出改善的润湿性和合适的机械性能(最终拉伸强度为 3-5 MPa)。通过使用模拟体液进行溶解测试,证实了通过添加生物活性玻璃提高了纤维垫的​​生物活性。此外,使用人类皮肤成纤维细胞和人类角质形成细胞样 HaCaT 细胞的细胞生物学测试表明,制造的复合纤维垫具有用作伤口敷料的潜力,特别是由于生物活性玻璃的存在能够支持伤口闭合的能力。此外,基于抗菌测试的结果,很明显需要优化电纺纤维垫来开发适合治疗感染伤口的伤口敷料。通过使用模拟体液进行溶解测试,证实了通过添加生物活性玻璃提高了纤维垫的​​生物活性。此外,使用人类皮肤成纤维细胞和人类角质形成细胞样 HaCaT 细胞的细胞生物学测试表明,制造的复合纤维垫具有用作伤口敷料的潜力,特别是由于生物活性玻璃的存在能够支持伤口闭合的能力。此外,基于抗菌测试的结果,很明显需要优化电纺纤维垫来开发适合治疗感染伤口的伤口敷料。通过使用模拟体液进行溶解测试,证实了通过添加生物活性玻璃提高了纤维垫的​​生物活性。此外,使用人类皮肤成纤维细胞和人类角质形成细胞样 HaCaT 细胞的细胞生物学测试表明,制造的复合纤维垫具有用作伤口敷料的潜力,特别是由于生物活性玻璃的存在能够支持伤口闭合的能力。此外,基于抗菌测试的结果,很明显需要优化电纺纤维垫来开发适合治疗感染伤口的伤口敷料。使用人类皮肤成纤维细胞和人类角质形成细胞样 HaCaT 细胞进行的细胞生物学测试表明,制造的复合纤维垫具有用作伤口敷料的潜力,特别是由于生物活性玻璃的存在支持伤口闭合的能力。此外,基于抗菌测试的结果,显然需要优化静电纺丝纤维垫,以开发适合治疗感染伤口的伤口敷料。使用人类皮肤成纤维细胞和人类角质形成细胞样 HaCaT 细胞进行的细胞生物学测试表明,制造的复合纤维垫具有用作伤口敷料的潜力,特别是由于生物活性玻璃的存在支持伤口闭合的能力。此外,基于抗菌测试的结果,很明显需要优化电纺纤维垫来开发适合治疗感染伤口的伤口敷料。
