Morphology and surface characterization of fabricated scaffolds. a–c SEM view of MNPs-free PCL/Collagen scaffolds at different resolutions (sized 200–500 nm). d–f SEM view of MNPs + PCL/Col I scaffolds at different resolutions. Scale bars equal 50, 20 and 1 µm, respectively. 2D and 3D topography of nanocomposite scaffolds whiteout (g), and with MNPs (h) via AFM at room temperature
