Spontaneous formation of dye-functionalized gold nanoparticles using reverse micellar systems.

Synthesis, Characterization, and SERS Functionalization of Hollow Gold Nanoparticles

Hollow gold nanoparticles formed by galvanic replacement reactions have been extensively studied because their increased surface area and tunable optical properties have applications in catalysis, drug delivery, and photothermal cancer therapies. In this study, hollow gold nanoparticles (size 30-40 nm) were synthesized by transmetallation of tyrosinereduced sacrificial solid silver nanospheres....

Synthesis and Functionalization of Gold Nanoparticles by Using of Poly Functional Amino Acids

Synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (L-Arginine and L-Aspartic acid) are reported. The gold nanoparticles were reduced by sodium citrate and functionalized with L-Arginine at the pH of 7 and 11 and L-Aspartic acid at the pH of 7. Transmission electron microscopy, UV-Vis spectroscopy, dynamic light scattering, zeta p...

Green Synthesis, Characterization and Application of Proanthocyanidins-Functionalized Gold Nanoparticles

Green synthesis of gold nanoparticles using plant extracts is one of the more promising approaches for obtaining environmentally friendly nanomaterials for biological applications and environmental remediation. In this study, proanthocyanidins-functionalized gold nanoparticles were synthesized via a hydrothermal method. The obtained gold nanoparticles were characterized by ultraviolet and visib...

Targeting and detecting cancer cells using spontaneously formed multifunctional dendrimer-stabilized gold nanoparticles.

We develop a facile approach to fabricating multifunctional dendrimer-stabilized gold nanoparticles (Au DSNPs) for cancer cell targeting and imaging. In this work, amine-terminated generation 5 (G5) poly(amidoamine) (PAMAM) dendrimers pre-functionalized with folic acid (FA) and fluorescein isothiocyanate (FI) are complexed with Au(III) ions, followed by acetylation of the amine groups on the de...
