The goal of the current work was to create an antibacterial agent by using polycaprolactone/chitosan (PCL/CH) nanofibers loaded with fruit extract (CMFE) as an antimicrobial agent for wound dressing. Several characteristics, including morphological, physicomechanical, and mechanical characteristics, surface wettability, antibacterial activity, cell viability, and in vitro drug release, were investigated. The inclusion of CMFE in PCL/CH led to increased swelling capability and maximum weight loss. The SEM images of the PCL/CH/CMFE mat showed a uniform topology free of beads and an average fiber diameter of 195.378 nm. Excellent antimicrobial activity was shown towards (31.34 ± 0.42 mm), (30.27 ± 0.57 mm), (21.31 ± 0.17 mm), (27.53 ± 1.53 mm), and (22.17 ± 0.12 mm) based on the inhibition zone assay. The sample containing 5 wt% CMFE had a lower water contact angle (47 ± 3.7°), high porosity, and high swelling compared to the neat mat. The release of the 5% CMFE-loaded mat was proven to be based on anomalous non-Fickian diffusion using the Korsmeyer-Peppas model. Compared to the pure PCL membrane, the PCL-CH/CMFE membrane exhibited suitable cytocompatibility on L929 cells. In conclusion, the fabricated antimicrobial nanofibrous films demonstrated high bioavailability, with suitable properties that can be used in wound dressings.
本研究旨在利用载有水果提取物(CMFE)的聚己内酯/壳聚糖(PCL/CH)纳米纤维制备一种抗菌剂,用作伤口敷料的抗菌剂。对包括形态、物理机械和力学特性、表面润湿性、抗菌活性、细胞活力和体外药物释放在内的几种特性进行了研究。CMFE 的加入增加了 PCL/CH 的溶胀能力和最大失重。PCL/CH/CMFE 垫的 SEM 图像显示出均匀的拓扑结构,无珠状且平均纤维直径为 195.378nm。基于抑菌圈试验,对 (31.34±0.42mm)、 (30.27±0.57mm)、 (21.31±0.17mm)、 (27.53±1.53mm)和 (22.17±0.12mm)显示出优异的抗菌活性。与纯垫相比,含有 5wt%CMFE 的样品具有较低的水接触角(47±3.7°)、高孔隙率和高溶胀性。基于 Korsmeyer-Peppas 模型,证明了 5%CMFE 负载垫的释放是基于异常非 Fickian 扩散。与纯 PCL 膜相比,PCL-CH/CMFE 膜在 L929 细胞上表现出良好的细胞相容性。总之,所制备的抗菌纳米纤维膜具有高生物利用度和适宜的性能,可用于伤口敷料。
