چکیده

In the current research, a novel poly(ε-caprolactone) nanofibrous composite scaffold including CZF-NPs1 (cobalt‑zinc ferrite nanoparticles) was investigated to study the physical, mechanical and biological properties of new magnetic nanofibrous materials and then to evaluate the effect of applied electromagnetic field on biological properties of these scaffolds. It was observed that the incorporation of CZF-NPs up to 3 wt.% leads to decrease in nanofibers' diameter to 466 nm. By raising the content of CZF-NPs, hydrophilicity and biodegradation of magnetic nanofibrous scaffolds improved significantly. In addition, the mechanical properties of nanofibers such as stress at break point was interestingly increased in the sample with 3 wt.% of CZF-NPs. The results of biocompatibility, cell adhesion and cell staining assays with L929 cells are much more improved in nanofibers embedded with CZF-NPs in the presence of external electromagnetic field (EMF). According to this study, magnetic nanofibrous scaffolds composed of PCL/CZF-NPs could be considered as a promising candidate to regenerate damaged tissues.
