Adsorption of Organic Molecules on Gold Electrodes

The Journal of Physical Chemistry C, 2007
We develop a simple approach to investigate the stability of an organic adlayer on a gold surface in the presence of an external voltage. All atoms are treated explicitly, and there is no predefined bond connectivity between the metal and the organic phase so that molecules are able to slide on the surface.

The gold foil electrode in pattern electroretinography

Documenta Ophthalmologica, 1994
A recent study found that the gold foil electrode produces large pattern electroretinogram amplitudes, but the test-retest reliability was low. In a three-center study, we observed that 90% of 29 patients who were tested with gold foil electrodes used three times appeared to have markedly lower amplitudes than when tested with new electrodes during the

The Gold Ring Electrode In Electroretinography

Archives of Ophthalmology, 1961
The introduction of the scleral type of contact lens electrode by Riggs in 1941 made it possible to record the electroretinogram (ERG) in human beings without apparent discomfort. As a result, literature on clinical ERG is steadily accumulating. However, with growing effort and experience, deficiencies in the contact lens electrode have become apparent

Electrospun gold nanofiber electrodes for biosensors

Biosensors and Bioelectronics, 2011
A new form of high surface area bioelectrode, based on nanofibers of electrospun gold with immobilized fructose dehydrogenase, was developed. The gold fibers were prepared by electroless deposition of gold nanoparticles on an electrospun poly(acrylonitrile)-HAuCl(4) fiber.

Breakdown of a gold nanowire between electrodes

Nanotechnology, 2007
Deformation behavior of an atomic Au wire placed between Au electrodes was investigated by using a generalization of the method of linear muffin-tin orbitals (LMTO) within the local-density approximation (LDA). We studied the dynamical motion of the atoms in the wire. Soft phonon modes were studied.

Electrogenerated Chemiluminescence of Luminol on a Gold-Nanorod-Modified Gold Electrode

The Journal of Physical Chemistry B, 2006
Electrogenerated chemiluminescence (ECL) of luminol on a gold-nanorod-modified gold electrode was studied, and five ECL peaks were obtained under conventional cyclic voltammetry in both neutral and alkaline solutions. Among them, four ECL peaks (ECL-1-4) were also observed on a gold-nanosphere-modified gold electrode, but the intensities of these ECL ...

Gold foil electrodes: A two-center study of electrode reliability

Documenta Ophthalmologica, 1994
Using the routine techniques employed at our two centers for recording pattern electroretinograms and a variety of methods, we investigated the reliability of the gold foil electrode over repeated uses. We found no significant difference between the pattern electroretinograms recorded with new electrodes and those that had had such extensive use in ...

Submicron Electrode Gaps Fabricated by Gold Electrodeposition at Interdigitated Electrodes

Key Engineering Materials, 2014
Electrodes with submicron gaps are desired for achieving high amplication redoxcycling sensors. In this contribution we report the use of electrodeposition of gold in order todecrease the inter-electrode spacing at interdigitated electrodes. Using this method submicronspacings can be obtained without expensive techniques such as e-beam lithography or ...

Electrocatalytic oxidation of glucose on gold–platinum nanocomposite electrodes and platinum-modified gold electrodes

Synthetic Metals, 2007
Abstract Electrochemical oxidation of glucose on gold–platinum nanocomposite electrodes and platinum-modified gold electrodes was investigated with cyclic voltammetry. Gold–platinum nanoparticles were prepared by reducing aqueous solutions containing chlorauric acid and chloroplatinic acid, and the electrodes were obtained by depositing the gold ...

Oxygen electroreduction on polycrystalline gold electrodes and on gold nanoparticle-modified glassy carbon electrodes

Journal of Solid State Electrochemistry, 2014
The oxygen reduction reaction (ORR) in acid media can be catalyzed on gold electrodes when the surface is activated by mechanical or electrochemical pretreatments. The activation is caused by increased surface roughness and defects, or asperities.
