Au(III)–PAMAM Interaction and Formation of Au–PAMAM Nanocomposites in Ethyl Acetate

Imaging and Therapeutic Applications of Optical and Thermal Response of SPION-Based Third Generation Plasmonic Nanodendrimers

“…Based on these results and other researcher suggestions, on the presence of NaBH 4 , the ions interact with surface amine group of magnetodendrimer [23] [38] [40] [43] and forms larger particles in the expense of smaller particles [35] [40]. When hydrazine sulfate was used as a reducing agent, the homogeneous distribution and smaller particles were obtained which could be explained as an entrapment and formation of Au-NPs on the cavity of magnetodendrimer [43].…”

Effects of Various Thiol Molecules Added on Morphology of Dendrimer–Gold Nanocomposites

“…One can see that most of the gold nanoparticles are greater than the hydrodynamic diameter (2.2 nm) (5) of G1.5, while in the case of G5.5 the particle size of gold obtained is smaller than the hydrodynamic diameter (7.4 nm) (5) of G5.5. Furthermore, from the measurements of FT-IR and UV-vis spectra it has been suggested that the structure of dendrimer-gold nanocomposites consists of gold nanoparticles of the exterior type for G1.5, while the structure consists of gold nanoparticles of a mixed type of interior and exterior for G5.5 (5). Thus, it is found that the structure of dendrimer-gold nanocomposites is considerably influenced by the generation of dendrimer.…”

“…For example, in the preparation of gold nanoparticles in the presence of poly(amidoamine) dendrimers (PAMAM) with surface methyl ester groups in ethyl acetate, it is suggested that gold nanoparticles are covered by lower generation dendrimers, while in the case of higher generation dendrimers gold nanoparticles are mainly formed inside the dendrimers (5). Similar structures for dendrimer-gold nanocomposites against the generation of dendrimers by means of SAXS and SANS have been characterized (4).…”

Multifunctional Nanoplatform for Targeted Laser-induced Hyperthermia and Microscopy of Breast Cancer Cells using SPION-based Gold and Folic Acid Conjugated Nanodendrimers: An in vitro Assay

“…This is thought to be due to interaction of such nanoparticles with surface amine group of dendrimers hence forming a larger particles in the expense of smaller particles [44,45]. When hydrazine sulfate was used as a reducing agent, smaller particles with a homogeneous distribution was obtained which could be readily entrapped within the MDs cavity [46]. In order to evaluate the formation of folic, the UV-Vis spectra of the samples were recorded.…”
