FIG. 5.

SEM images of mineral-coated scaffolds embedded and sectioned in methyl methacrylate (MMA), coated PLLA (a) and coated PCL (b). The magnified areas of yellow boxes are also shown, coated PLLA (c) and coated PCL (d). Images show that mineral layers as white color and polymers, scaffold and MMA, as dark gray. The mineral layers existed on the surface of porous scaffolds within coated PLLA and PCL scaffolds.
