Figure 3

High and low magnification SEM images and EDS of the surface and inner-sections of PILP-mineralized collagen samples using 14-kDa poly-L-aspartic acid as the polymer directing agent. (A, B) SEM and (C) EDS of the surface of a mineralized collagen sponge treated with PILP solution containing 50 µg/mL PASP for 3 days. (D, E) SEM and (F) EDS of the inner-section of a mineralized collagen sponge treated with PILP solution containing 50 µg/mL PASP for 3 days. (G, H) SEM showing the inner-section of a mineralized collagen sponge treated with PILP solution containing 50 µg/mL PASP for 6 days. The external surface had the same appearance. (I) Corresponding EDS plot of the inner-section of PILP mineralized sample after 6 days.
