Synthesis and characterization of gold nanocomposites with modified and intact polyamidoamine dendrimers

In vitro Cytotoxicity Effects of 197Au/PAMAMG4 and 198Au/PAMAMG4 Nanocomposites Against MCF7 and 4T1 Breast Cancer Cell Lines

“…26-28 Firstly 0.5μmol dendrimer was added to 5 mL of water with vigorously stirring. Then 5 mL of an aqueous solution of 0.5 μmol HAuCl 4 was added to the above solution.…”

Nanoporous Nanocomposite Hydrogels Composed of Polyvinyl Alcohol and Na-montmorillonite

“…[24] Nanocomposite hydrogels are reinforced hydrophilic three-dimensional networks consisting of at least a cross-linked polymeric matrix and a nanoscale reinforcing agent. [25] Different types of nanostructured particles, e.g., gold, [26] silver, [27] iron oxide, [28] carbon nanotubes, [29] and various kinds of clays, e.g., laponite, [30,31] montmorillonite, [32,33] hydrotalcite, [34] and bentonite, [35] have been used to produce nanocomposite hydrogels. Nanocomposite hydrogels have been utilized successfully in numerous practical applications such as sensor and actuator systems, [36] oil recovery, [37] biomedical scaffolds, [38] drug delivery devices, [39,40] and wound dressing systems.…”

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

“…In our recent report [48], we indicated that all samples have a unique absorption peak in the range of 520-540 nm which reveals the formation of AuNPs. However, other peaks at 280 nm and 320 nm also correspond to Au-NPs aggregation [49,50]. Recently, we reported that the absorption band between 320-370 nm indicates the formation of nanosized magnetite particles and the intensity of the light scattered depends on the polarizability and that in turn depends on the molecular weight [41].…”
