Synthesis of Au core Au/Ag alloy shell nanoparticles using branched Au nanoparticles as seeds

CrystEngComm, 2011
Novel Au core Au/Ag alloy shell particles denoted as Au@Au/Ag were prepared through the following two-step reduction method using branched Au nanoparticles as seeds. In the first step, branched Au seeds were prepared from an aqueous solution of an HAuCl4/ammonium formate (AF)/poly(vinylpyrrolidone) (PVP) mixture.

Functionalization of Elongated Tetrahexahedral Au Nanoparticles and Their Antimicrobial Activity Assay.

ACS Applied Materials and Interfaces, 2019
Gold nanoparticles are inert for the human body, and therefore, they have been functionalized to provide them with antibacterial properties. Here, elongated tetrahexahedral (ETHH) Au nanoparticles were synthesized, characterized, and functionalized with ...

Nonhomogeneous surface premelting of Au nanoparticles

Nanotechnology, 2008
A reversible nonhomogeneous surface premelting of Au nanoparticles is demonstrated through molecular dynamics simulations. With increasing temperature, liquid-like atoms first appear at some vertices and edges of surface facets, then small liquid regions grow and, at temperatures close to the particle melting temperature, most of the remaining solid ...

Radiotherapy Improvements by Using Au Nanoparticles

Recent Patents on Nanotechnology, 2015
Au nanoparticles can be prepared inside biological solutions and incorporated in special molecules for their transport through blood, drugs and proteins up to the tumour sites or directly injected in their volume when it is possible. The Au nanoparticles are biocompatible and can be accepted locally in the organism also at relatively high ...

Electrified Selective “Sponges” Made of Au Nanoparticles

Journal of the American Chemical Society, 2010
Imprinted Au nanoparticle (NP) composites are assembled on Au surfaces by the electropolymerization of thioaniline-functionalized Au NPs in the presence of the imprint molecules, picric acid (1), N,N'-dimethyl-4,4'-bipyridinium (2), and N,N'-dimethylbipyridinium-4,4'-ethylene dichloride (3).

Optical nonlinearities of Au nanoparticles and Au/Ag coreshells

Optics Letters, 2009
Au nanoparticles exhibited both negative and positive nonlinear absorptions with ground-state plasmon bleaching and free-carrier absorption that could be origins of the saturable and reverse-saturable optical properties. Au/Ag coreshells displayed only positive nonlinear absorption and reverse-saturable optical properties as a function of excitation ...
