Figure 3. APT data reconstructions of HAP nanoparticle-containing samples. (A) Global view of an Al2O3 data reconstruction, showing Al atoms (only 20% are shown for clarity) and 3.4% Ca isosurfaces that show the location of the nanoparticles; (B) Global view of a HAP nanoparticle encapsulated in gold, showing Au (30% shown) and Ag atoms indicating the coating/matrix, as well as 2.6% Ca, indicating the location of a single HAP nanoparticle. APT: Atom probe tomography; HAP: Hydroxyapatite.
