Radiolytic synthesis and characterization of PVA/Au nanocomposites: The influence of pH values [PDF]

open access: yesHemijska Industrija, 2008
Nanocomposites which consist of polymer matrix and nanoparticles of noble metal are a very important class of nanomaterials. The optical properties of these materials are strongly dependent on the nanoparticles size as well as on the synthesized ...

Effect of Ar Gas Pressure on LSPR Property of Au Nanoparticles: Comparison of Experimental and Theoretical Studies

open access: yesNanomaterials, 2020
In this study, the thin films were produced by using pulsed laser deposition (PLD) technique from gold (Au) nanoparticles deposited on two kinds of substrates under different argon (Ar) gas pressure.

Designing caps for colloidal Au nanoparticles

open access: yesChemical Science, 2021
We show that active surface growth is an effective method to create structural variety in the appending domain of Au seeds. The dynamic competition between the growth sites led to different Au hats on seeds.

Collagen Cross-Linking with Au Nanoparticles [PDF]

open access: yesBiomacromolecules, 2008
Tiopronin (N-(2-mercaptopropionyl)glycine)-protected gold nanoparticles (TPAu) were cross-linked to collagen via EDC (1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide) coupling. On average, each TPAu forms eight amide bonds with collagen lysine moieties. The resulting gels were studied with environmental SEM, TEM, micro-DSC, and TNBS assay.

Production of Au/phosphonium polymer nanoparticles

open access: yesEuropean Polymer Journal, 2021
Abstract The introduction of cationic groups onto the surface of gold nanoparticles (GNPs) is a valuable synthetic technique with many applications. This study reports the synthesis of the functionalization of GNPs with phosphonium groups presented in the ring opening metathesis (ROMP)-type polymer backbone.

Shell Thickness-Dependent Strain Distributions of Confined Au/Ag and Ag/Au Core-Shell Nanoparticles

open access: yesAdvances in Condensed Matter Physics, 2015
The shell thickness-dependent strain distributions of the Au/Ag and Ag/Au core-shell nanoparticles embedded in Al2O3 matrix have been investigated by finite element method (FEM) calculations, respectively.

Magnetic Au Nanoparticles on Archaeal S-Layer Ghosts as Templates

open access: yesNanomaterials and Nanotechnology, 2011
Cell‐ghosts representing empty cells of the archaeon Sulfolobus acidocaldarius, consisting only of their highly ordered and unusually stable outermost proteinaceous surface layer (S‐layer), were used as templates for Au nanoparticles ...

Collision-spike Sputtering of Au Nanoparticles [PDF]

open access: yesNanoscale Research Letters, 2015
Ion irradiation of nanoparticles leads to enhanced sputter yields if the nanoparticle size is of the order of the ion penetration depth. While this feature is reasonably well understood for collision-cascade sputtering, we explore it in the regime of collision-spike sputtering using molecular-dynamics simulation.

Synthesis and application of Fe3O4@Au composite nanoparticles as magnetic resonance/computed tomography dual-modality contrast agent

open access: yesJournal of Medical Signals and Sensors, 2020
Background: None of the molecular imaging modalities can produce imaging with both anatomical and functional information. In recent years, to overcome these limitations multimodality molecular imaging or combination of two imaging modalities can provide ...
