SEM/EDS and TEM micrographs of PILP-mineralized collagen samples using 27-kDa poly-L-aspartic acid as the polymer directing agent. SEM of the surface (A) and the inner-section (B) of a mineralized collagen sponge treated with PILP solution containing 50 µg/mL PASP27 for 3 days. (C) EDS of the inner-section of a mineralized collagen sponge treated with PILP solution containing 50 µg/mL PASP27 for 3 days. (D) Bright- and (E) Dark-field TEM micrographs of an isolated PILP-mineralized collagen fibril. Bar = 100 nm. The dark-field image was constructed by selecting the (002) arc with the objective aperture from the SAED pattern shown in (F).
