Hot Hole Photoelectrochemistry on Au@SiO₂@Au Nanoparticles

The Journal of Physical Chemistry Letters, 2017
There is currently a worldwide need to develop efficient photocatalytic materials that can reduce the high-energy cost of common industrial chemical processes. One possible solution focuses on metallic nanoparticles (NPs) that can act as efficient absorbers of light due to their surface plasmon resonance.

Au nanoparticles coated with chitosan

Colloid and Polymer Science, 2019
This paper describes a method of coating metallic gold (Au) nanoparticles with chitosan (CS) shells in an aqueous solution. A colloidal solution of Au nanoparticles with a particle size of 16.5 ± 1.7 nm was prepared by reducing the Au ions (III) with sodium citrate in water at 80 °C.

Au nanoparticles target cancer

Nano Today, 2007
Nanoparticles with unique optical properties, facile surface chemistry, and appropriate size scale are generating much enthusiasm in molecular biology and medicine. Noble metal, especially Au, nanoparticles have immense potential for cancer diagnosis and therapy on account of their surface plasmon resonance (SPR) enhanced light scattering and ...

Au nanoparticle-imprinted polymers

Chemical Communications, 2005
Au nanoparticles protected with a polymerisable ligand were incorporated into bulk macroporous polymers; etching the metal core resulted in disulfide-lined, nanometre-scale cavities capable of recognising similarly-sized Au particles.

Phospholipid-Stabilized Au−Nanoparticles

Biomacromolecules, 2005
This communication outlines a simple two-step approach of modification of 1 nm diameter Au nanoparticles using an aqueous solution of (1,2-dipalmitoyl-sn-glycero-3-phosphothio-ethanol) phospholipid (PL). Transmission electron microscopy as well as particle size analysis show that, as a result of PL reactions with Au particles, the initial Au ...

Plasmonic Au Nanoparticles Incorporated in the Zeolitic Imidazolate Framework (ZIF-67) for the Efficient Sunlight-Driven Photoreduction of CO2

, 2020
Nowadays, charge separation and efficient solar-light absorption are the main challenges in the photoreduction of CO2. Although significant efforts have been made to overcome these issues, including the use of cocatalysts and doping, photocatalysts still

Spin-labelled Au nanoparticles

Faraday Discussions, 2004
A series of Au nanoparticles functionalised with nitroxide spin labels has been prepared and studied by EPR spectroscopy. Samples with low coverage of the spin label were used to investigate the dynamics of the surface-attached labels at different distances from the Au surface. The rotational correlation times of spin labels vary from 10(-10) s to more
