Anodic behavior of clioquinol at a glassy carbon electrode

Bioelectrochemistry, 2011
Clioquinol is an antifungal, antiprotozoal and an Alzheimer's disease drug with cytotoxic activity toward human cancer cells. The electrochemical behavior of clioquinol and its oxidation product was studied using cyclic, differential pulse and square-wave voltammetry over a wide pH range on a glassy carbon electrode.

Redox behavior of biofilm on glassy carbon electrode

Bioelectrochemistry, 2011
Marine and freshwater biofilm usually shift the open circuit potential (OCP) of stainless steel towards the electropositive direction by +450 mV vs SCE. The nature of oxide film and bacterial metabolism were also correlated with ennoblement process by various investigators.

Glassy Carbon Ceramic Composite Electrodes

Analytica Chimica Acta, 2006
A new carbon composite electrode material, based on dispersing glassy carbon (GC) microparticles into methyltrimethoxysilane-derived sol, is described in the present paper. The resulting glassy carbon ceramic composite electrodes (GCCEs) combine the electrochemical properties of GC with the advantages of composite electrodes, and thus offer high ...

Voltammetric determination of pentachlorophenol at a glassy carbon electrode

The Analyst, 1988
An electroanalytical study of the pentachlorophenol oxidation process at a glassy carbon electrode in aqueous solution using different voltammetric techniques has been carried out. The results obtained by differential-pulse voltammetry allowed a method to be developed for the determination of pentachlorophenol in the ranges 1.0 × 10–5–10.0 × 10–5 and 2.

Measurements on glassy-carbon electrodes in saline

Medical & Biological Engineering & Computing, 1977
Results of measurements on glassy carbon used as physiological measuring electrodes and as stimulating electrodes are presented. The frequency dependence of the electrode impedance is shown to be comparable with that of metallic electrodes. Because of its inertness to body tissue, the glassy carbon electrode appears to have favourable properties for ...

Electrochemical study of ricin at glassy carbon electrode

The Analyst, 2013
Ricin, Ricinus communis agglutinin 60 - RCA 60, is a deadly phytotoxic protein which inhibits ribosomes (class II), and there is no known effective antidote in living organisms. Ricin is composed of two polypeptide chains, A and B, linked covalently by a single disulfide bond.

A Microcell for Stripping Analysis With Glassy Carbon and Mercury-Plated Glassy Carbon Electrodes

Analytical Letters, 1973
Abstract A microcell has been constructed for stripping analysis in solution volumes as low as 5 μl, employing a glassy carbon or mercury-plated glassy carbon working electrodes and a three electrode system. Using normal d.c. stripping techniques, as little as 100 picograms of mercury and 10 picograms of lead can be determined.

Vertically Aligned Carbon Nanotube Electrodes Directly Grown on a Glassy Carbon Electrode

ACS Nano, 2011
Three-dimensional microelectrodes were fabricated using glassy carbon electrodes combined with vertically aligned carbon nanotubes (VACNTs). VACNTs were grown on various conducting electrode patterns including a carbon electrode fabricated by pyrolysis of a negative photoresist, with plasma-enhanced chemical vapor deposition using a bilayer Fe/Al ...

Amperometric Glucose Biosensors Based on Glassy Carbon and SWCNT‐Modified Glassy Carbon Electrodes

Electroanalysis, 2007
AbstractDifferent carbonaceous materials, such as single‐walled carbon nanotubes (SWCNTs) and glassy carbon submitted to an electrochemical activation at +1.80 V (vs. SCE) for 900 s, have been used with the aim of comparing their performances in the development of enzyme electrodes.

Modification of Glassy Carbon Electrode with Pyridine

ECS Transactions, 2011
Glassy carbon electrodes were modified with pyridine by electrografting of the corresponding in situ generated diazonium cations. The diazonium cations formation from the 3-aminopyridine in acid media at room temperature was confirmed by UV spectroscopy. The presence of immobilized pyridine at the electrode surface was demonstrated by XPS measurements.
