Comparison of the voltammetric behavior of metronidazole at a DNA‐modified glassy carbon electrode, a mercury thin film electrode and a glassy carbon electrode [PDF]
Electroanalysis, 1997 AbstractThe electroanalytical performance at three electrodes: DNA‐modified galssy carbon electrode, mercury thin film electrode and glassy carbon electrode, for the study of the electrochemical reduction of metronidazole is compared. All three electrodes showed a similar trend in the reduction mechanism for metronidazole, depenent on pH in the acid ...

Electrochemical behaviour of isatin at a glassy carbon electrode [PDF]
Analytica Chimica Acta, 2006 The electrochemical behavior of isatin--a molecule with a broad range of applications in synthetic, biological and clinical activity--has been investigated over a wide pH range at a glassy carbon electrode (GCE) using cyclic, square wave and differential pulse voltammetry. The oxidation of isatin is an irreversible process, pH dependent and occurs with

Determination of Caffeine at a Nafion‐Covered Glassy Carbon Electrode
Electroanalysis, 2007 AbstractA simple differential pulse voltammetric method based on a Nafion‐covered glassy carbon electrode was developed for the quantitative determination of caffeine in cola beverages. The modified electrode exhibits a clear improvement of the current response compared to that observed at a bare glassy carbon electrode.

EDTA modified glassy carbon electrode: Preparation and characterization
Electrochimica Acta, 2009 Abstract EDTA-phenoxyamide modified glassy carbon electrode (EDTA-GC) was prepared at a glassy carbon electrode by surface synthesis. In the first step, nitrophenyl was grafted to the glassy carbon (GC) surface via the electrochemical reduction of its tetraflouroborate diazonium salt.
