In this study, an electrospinning technique was used for the fabrication of novel biomedicated nanofibers which are applied for preventing wound infections and local chemotherapy. CURs containing nanofibers with a crosslinking agent (Si-O-Si network) have been produced through functionalization of graphene oxide with APTES. In vitro drug release profile results showed the novel nanofibers could limit the drug's initial burst release and provide better sustainability in comparison with the blend nanofibers without modified GO. The novel delivery vehicle can inhibit the growth of MRSA and S. epidermidis up to 94% and 88%. Also in vitro cell toxicity experiments which were performed by XTT method on MCF-7, HEP G2 and L929 cell lines showed that anticancer activity of CUR remained intact even after loading into nanofibers. This result suggested that the fGO-Si-CUR including nanofibers were a promising candidate for postoperative chemotherapy.
在这项研究中,使用静电纺丝技术制造了新型的生物医学纳米纤维,用于预防伤口感染和局部化疗。通过用 APTES 对氧化石墨烯进行功能化,将含有交联剂(Si-O-Si 网络)的 CUR 包含在纳米纤维中。体外药物释放曲线结果表明,与未经修饰的 GO 的共混纳米纤维相比,新型纳米纤维可以限制药物的初始突释,并提供更好的可持续性。新型给药载体可以抑制 MRSA 和表皮葡萄球菌的生长,达到 94%和 88%。此外,通过 XTT 法在 MCF-7、HEP G2 和 L929 细胞系上进行的体外细胞毒性实验表明,即使将 CUR 载入纳米纤维中,其抗癌活性仍然保持完整。这一结果表明,包含纳米纤维的 fGO-Si-CUR 是一种有前途的术后化疗候选药物。
