Direct Synthesis and Morphological Characterization of Gold-Dendrimer Nanocomposites Prepared Using PAMAM Succinamic Acid Dendrimers: Preliminary Study of the Calcification Potential

Figure 11

TEM micrographs providing morphostructural evidences on the formation of HA on the Au-G6-1 functionalized PHEMA surface; HA nanocrystals are formed around agglomerations of gold-dendrimer nanocomposites; (a) agglomerations of nanocomposites (area 1) are embedded in a mass of HA (area 2) formed following the incubation in SBF1.5x, while area 3 presents one nanocomposite particle with HA nanocrystals around and the inset 4 represents the SAED image with crystallographic planes characteristic to Au and HA; (b), (c) HR-TEM images presenting one nanocomposite nanoparticles identified through the typical crystallographic planes (111) surrounded by HA nanocrystals with their characteristic planes (002), (202), and (211).
