摘要

本文采用单喷嘴静电纺丝法制备了中空生物活性玻璃(BG)纳米纤维。通过SEM和TEM对制备的空心BG纳米纤维的形貌进行了观察，结果表明BG纳米纤维具有连续中空的内部结构。将中空BG纳米纤维置于模拟体液(SBF)中孵育，考察其磷灰石矿化能力，结果表明，孵育6 h后，中空BG纳米纤维表面出现花状磷灰石，傅里叶变换红外(FTIR)结果进一步证实了磷灰石的形成。结果表明，由于其独特的中空结构和生物活性，空心BG纳米纤维可用于药物输送和骨再生。

Preparation of hollow bioactive glass nanofibers by a facile electrospinning method

Abstract In this communication, hollow bioactive glass (BG) nanofibers were fabricated via a single-nozzle electrospinning method. The morphology of the prepared hollow BG nanofibers was observed by SEM and TEM, and the results showed that BG nanofibers had a continuous hollow interior. The hollow BG nanofibers were incubated in simulated body fluid (SBF) to investigate their apatitemineralization ability, and the result showed that after incubation for 6 h a flower-like apatite was observed on the surface of hollowBGnanofibers, and the Fourier transform infrared (FTIR) result further confirmed the formation of apatite. The results suggested that hollow BG nanofibers could be used for drug delivery and bone regeneration applications due to their unique hollow structure and bioactivity.
