Healing of various skin wounds is a lengthy process and often combined with bacterial infection and scar formation. Biomimetic electrospun nanofibrous wound dressing loaded with materials that possess properties of dual antibacterial and tissue repair would be developed to address this problem. In this study, a composite chitosan electrospun nanofibrous material containing Cur@β-CD/AgNPs nanoparticles composed of silver and curcumin possessed synergic effects on antibacterial activity and wound healing. The developed functionalized silver nanoparticles showed effective activity against both Gram-negative and Gram-positive bacteria. In vivo, Cur@β-CD/AgNPs chitosan dressing displayed enhanced wound closure rates compared to commercial AquacelAg. Moreover, Cur@β-CD/AgNPs chitosan dressing contributed to the most uniform collagen distribution by Masson's trichrome staining. In brief, Cur@β-CD/AgNPs chitosan nanofibers work as a potential wound dressing with antibacterial and antiscarring properties.
各种皮肤创伤的愈合是一个漫长的过程,往往伴随着细菌感染和疤痕形成。为了解决这个问题,我们开发了一种仿生电纺纳米纤维创伤敷料,负载具有双重抗菌和组织修复性能的材料。在这项研究中,一种包含 Cur@β-CD/AgNPs 纳米粒子的壳聚糖复合电纺纳米纤维材料,由银和姜黄素组成,具有协同的抗菌活性和伤口愈合作用。所开发的功能化银纳米粒子对革兰氏阴性和革兰氏阳性菌均表现出有效的活性。在体内,Cur@β-CD/AgNPs 壳聚糖敷料的伤口闭合率比商业 AquacelAg 显著提高。此外,Cur@β-CD/AgNPs 壳聚糖敷料通过 Masson 三色染色有助于最均匀的胶原蛋白分布。总之,Cur@β-CD/AgNPs 壳聚糖纳米纤维作为一种具有抗菌和抗瘢痕形成特性的潜在创伤敷料。
