Characteristics of magnetic scaffolds: (a-f) SEM images at different magnifications, (g) EDS atomic signal, (h) XRD phase analysis and (i) FT-IR chemical groups.

Low (a-c, 150 X) and high (d-f, 1000 X) SEM morphologies of PCL, PCL–MNPs 5%, and PCL–MNPs 10% scaffolds showing a highly porous structure, and their EDS results showing existence of MNPs (Fe) on the surface, which was also confirmed by XRD and FT-IR spectrum.
