Figure 2: Photograph and SEM images of the PCL porous scaffolds. The substrates were produced by using NaCl/PCL (30 % wt/v) composition realized with sieved salt crystals with diameters between 140-380 μm (A, D), minus of 140 μm (B, E) and PCL without salts (C, F). In A, B and C ruler represented cm; in D, E, F scale bars equals 100 μm.
