Direct Synthesis and Morphological Characterization of Gold-Dendrimer Nanocomposites Prepared Using PAMAM Succinamic Acid Dendrimers: Preliminary Study of the Calcification Potential
Figure 2
TEM and HR-TEM images presenting the influence of dendrimer concentration over the dimension of Au-G2-5 ((a) and (b); scalebar 20 nm) and Au-G2-2.5 ((c)–(e); scalebar 2 nm). (a), (c), (e) General views with insets presenting representative SAED patterns for gold (fcc); (b) two Au-G2-5 highly crystalline nanoparticles coated by a thin organic exterior shell; (d) two small but still crystalline Au-G2-2.5 nanoparticles onto the surface of a larger particle; (e) different populations of particles coexist; the small particles are more numerous; spherical entities around 3.8 nm are visible; (f) selected area from (e). Corresponding histograms of the particles size distribution are also included ((g), (h)). (i) EDX spectrum as recorded for Au-G2-2.5.
