The polymer poly(ε-caprolactone) (PCL) has been used in the biomaterial field for its relatively inexpensive price and suitability for modification. Also, its chemical and biological properties are desirable for biomedical applications. The electrospinning process has been used for producing polymer fibers of PCL due in large part to an increased interest in nanoscale properties and technologies. Moreover, the use of biocompatible polymers for the viability of cell growth is a promising alternative to improve osseointegration. Characterization techniques such as scanning electron microscopy and contact angle were used for analyses of samples. Adult human dermal fibroblasts (neonatal) were utilized to evaluate the biocompatibility of the association of the electrospinning process of the biocompatible polymer (PCL) with TiO nanotubes on the Ti-30Ta alloy surface. The results of this study showed a favorable response for adhesion on the surface. This promising material is due to the modulation of the biological response.
聚合物聚(ε-己内酯)(PCL)因其相对低廉的价格和适合改性而在生物材料领域得到应用。此外,其化学和生物学性质也适用于生物医学应用。静电纺丝工艺已用于生产 PCL 的聚合物纤维,这在很大程度上是因为人们对纳米级特性和技术越来越感兴趣。此外,使用生物相容性聚合物来提高细胞生长的活力是一种很有前途的方法,可以改善骨整合。扫描电子显微镜和接触角等特性技术用于对样品进行分析。利用成人皮肤成纤维细胞(新生儿)来评估生物相容性聚合物(PCL)的电纺丝工艺与 TiO 纳米管在 Ti-30Ta 合金表面的结合。这项研究的结果显示,表面的粘附反应良好。这种有前景的材料是由于生物反应的调节。
