FIG. 2.

Images, micro-computed tomography (μ-CT) images, and environmental scanning electron microscope (ESEM) images of coated PLLA (a, e, i, m), uncoated PLLA (b, f, j, n), coated PCL (c, g, k, o) and uncoated PCL (d, h, l, p). μ-CT images confirm that mineral layer covered the surface of both PLLA and PCL scaffolds (e, g). ESEM images show that rough surface of the coated PLLA and PCL scaffolds (m, o), while relatively smooth surface of the uncoated PLLA and PCL scaffolds (n, p).
