Scanning electron microscopy (SEM) and geochemical mapping by energy dispersive X-ray spectroscopy (EDS) of the LAPA/SBF-3-0081 sample. (a)—An overview of the internal section of the sample, showing the analyzed area (red box). (b)—Detail of the analyzed area, which indicates the specific region for SEM and EDS analyses (red box). (c, d)—Backscattering images of SEM where microchemical mappings were constructed. (e, f)—Calcium micro-mappings. (g, h)—Phosphorus micro-mappings. (i)—Microstructure in which bone fragments and breakages appear near osteocytes. (j)—SEM image details the bone structure and broken bone fragments inside the porous system. The yellow box details the bone structures. (k)—Detailed SEM image of the Haversian canals its hydroxyapatite structures. (l)—SEM image of the hydroxyapatite structures.
