Preparation of [C60]Fullerene Nanowhisker-gold Nanoparticle Composites and Reduction of 4-Nitrophenol through Catalysis

open access: yesNanomaterials and Nanotechnology, 2015
A gold nanoparticle solution was prepared by adding sodium borohydride (NaBH4), trisodium citrate dihydrate (C6H5Na3O7⋅2H2O), cetyltrimethyl ammonium bromide (CTAB,(C16H33)N(CH3)3Br), ascorbic acid (C6H8O6), and potassium tetrachloroaurate(III)(KAuCl4 ...

High-resolution surface plasmon imaging of gold nanoparticles by energy-filtered transmission electron microscopy [PDF]

open access: yes, 2009
We demonstrate the imaging capabilities of energy-filtered transmission electron microscopy at high-energy resolution in the low-energy-loss region, reporting the direct image of a surface plasmon of an elongated gold nanoparticle at energies around 1 eV.

Effect of Gold Nanoparticle Conjugation on Peptide Dynamics and Structure

open access: yesEntropy, 2012
Molecular dynamics simulations were used to characterize the structure and dynamics for several peptides and the effect of conjugating them to a gold nanoparticle. Peptide structure and dynamics were compared for two cases: unbound peptides in water, and

Peptide-Gold Nanoparticle Conjugates as Artificial Carbonic Anhydrase Mimics [PDF]

open access: yes, 2019
We herein describe the design and synthesis of a catalytically active peptide–gold nanoparticle conjugate (Pep-Au-NP) that binds Zn(II) within its peptide monolayer and develops carbonic anhydrase activity. Specifically, a modified variant of the β-sheet

Surface-Enhanced Plasmon Splitting in a Liquid-Crystal-Coated Gold Nanoparticle [PDF]

open access: yes, 2005
We show that, when a gold nanoparticle is coated by a thin layer of nematic liquid crystal, the deformation produced by the nanoparticle surface can enhance the splitting of the nanoparticle surface plasmon.

Sintering-Based In-Situ Synthesis and Characterization by TEM of Noble Metal Nanoparticles for Ceramic Glaze Color Control

open access: yesNanomaterials, 2021
Gold and silver salt mixtures are incorporated in ceramic glazes for in situ development of mixtures of gold and silver nanoparticles (NPs) that subsequently allow for a wide spectrum of low metal loading color control within ceramic materials.

Contrast Enhancement for Portal Imaging in Nanoparticle-Enhanced Radiotherapy: A Monte Carlo Phantom Evaluation Using Flattening-Filter-Free Photon Beams

open access: yesNanomaterials, 2019
Our team evaluated contrast enhancement for portal imaging using Monte Carlo simulation in nanoparticle-enhanced radiotherapy. Dependencies of percentage contrast enhancement on flattening-filter (FF) and flattening-filter-free (FFF) photon beams were ...

An Experimental Study on the Heat Enhancement and the Bio-Heat Transfer Using Gold Macro Road and Ultrasound: A Potential Alternative to Kill Cancer Cells [PDF]

open access: yes, 2014
We have previously proposed a method of treating solid tumors with a combination of gold macro-rods irradiated with ultrasound. Macro particle sized rods offer a greater circumferential treatment area over nanoparticle options.
