Figure 2

Elastomeric membrane and composite characterization. Microscopic images of the ((a)–(d)) PEA scaffolds with cylindrical orthogonal pores and ((e)–(h)) PCLMA scaffolds with spherical pores. ((a) and (e)) SEM images, cross section, and ((b) and (f)) SEM images, surface. ((c) and (g)) Congo Red staining and ((d) and (h)) cryoSEM images of the scaffolds loaded with 0.15% RAD16-I and gelled with PBS, surface. White arrows point out the elastomeric membrane while the black ones point out the self-assembling peptide structure after gel.
