Carbon Nanotube Purification:  Preparation and Characterization of Carbon Nanotube Paste Electrodes

Analytical Chemistry, 2003
Paste electrodes have been constructed using single-wall carbon nanotubes mixed with mineral oil. The electrochemical behavior of such electrodes prepared with different percentages of carbon nanotubes has been compared with that of graphite paste electrodes and evaluated with respect to the electrochemistry of ferricyanide with cyclic voltammetry ...

Detection of homocysteine at carbon nanotube paste electrodes

Talanta, 2004
The use of a carbon-nanotube paste (CNTP) electrode provides an effective means for the determination of homocysteine. A decrease of ca. 120mV in the overpotential for the oxidation of homocysteine compared to a traditional carbon paste electrode, is reported along with greatly enhanced signal-to-noise characteristics.

Comparative Electrochemical Study of Some Phenothiazines with Carbon Paste, Solid Carbon Paste and Glass-Like Carbon Electrodes

Collection of Czechoslovak Chemical Communications, 2000
In order to obtain modified electrodes with phenothiazines and to develop electrochemical methods for their determination in pharmaceutical formulations, promazine maleate, promethazine maleate and levomepromazine, were studied by linear sweep voltammetry using different types of working electrodes: carbon paste, solid carbon paste and glass-like ...

Cephalosporin antibiotics at carbon paste and modified carbon paste electrodes in both aqueous and biological media [PDF]

Bioelectrochemistry and Bioenergetics, 1995
Abstract A sensitive voltammetric method has been developed for the oxidation and determination of the cephalosporin antibiotics Cefatrexyl, Velosef, Claforan, Cefobid and Rocephin at both carbon paste and modified fatty acid carbon paste electrodes. The electroanalytical technique used was direct current stripping voltammetry.

Voltammetric determination of Celiptium with carbon paste and lipid-modified carbon paste electrodes [PDF]

Analytica Chimica Acta, 1990
Abstract The electrooxidation of the antitumour drug 2-methyl-9-hydroxyellipticinium (Celiptium) was investigated by cyclic, differential-pulse and adsorptive voltammetry at carbon paste (CPE) and lipid-modified carbon paste electrodes (LM-CPE). The influence of the paste composition, i.e., the ratio of graphite to binder, was studied in order to ...

Biocatalytic Carbon Paste Sensors Based on a Mediator Pasting Liquid

Analytical Chemistry, 2004
The preparation and advantages of a new generation of carbon paste enzyme electrodes where the redox mediator acts also as the pasting liquid are described. The mediator pasting liquid concept is illustrated for amperometric biosensing of glucose in connection with either the tert-pentylferrocene or n-butylferrocene mediator/binder along with the ...

Activated carbon paste electrodes for biosensors

Analytical Chemistry, 1994
A reagentless amperometric glucose biosensor was constructed using glucose oxidase and hydroquinone (H2Q) coimmobilized in carbon paste. The sensor response was studied by amperometry and cyclic voltammetry in quiescent solutions, as well as in a flow injection apparatus.

Voltammetric study of glibenclamide at carbon paste and Sephadex-modified carbon paste electrodes

Analytical and Bioanalytical Chemistry, 2004
The oxidative behaviour of the antidiabetic agent glibenclamide on a bare carbon paste electrode (CPE) and a Sephadex-modified carbon paste electrode (SMCPE) was explored by cyclic and differential pulse voltammetry (DPV). The analysis procedure consisted of an open circuit accumulation step in stirred sample solution of Britton-Robinson buffer (0.04 ...
