Acid Stability of Carbon Paste Enzyme Electrodes
Analytical Chemistry, 2006This note reports on the unusual protection of several enzymes against harsh pH conditions provided by carbon paste electrodes. Both glucose oxidase and polyphenol oxidase carbon paste amperometric biosensors display a remarkable resistance to acid deactivation compared to conventional biosensors prepared by electropolymeric entrapment of enzymes.

Carbon-Filled Polymer Paste Reference Electrodes
Analytical Letters, 1985Abstract Inexpensive, disposable, carbon-filled polymer paste reference electrodes are reported. These electrodes are designed for use in conjuction with carbon-filled polymer paste ion-selective probes reported earlier. Attachment of integrated electronics is easily achieved.

Voltammetric studies on carbon paste electrodes
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1984ABstract The relative importance of the carbon and the pasting liquid on the properties of the carbon paste electrode was studied using cyclic potential sweep voltammetry. The effect on electrode capacity and kinetics for the systems hexacyanoferrate (II) and hydroquinone in phosphate buffer of pH 6.8 was compared.

Zeolite-modified solid carbon paste electrodes
Journal of Solid State Electrochemistry, 2003New zeolite-modified carbon-based electrodes are described. They are based either on the physical anchoring of zeolite particles on the surface of solid carbon paste (the viscosity of which can be tuned by temperature change or controlled dissolution by an organic solvent), or on the dispersion of zeolite particles in the bulk of a carbon paste matrix ...

Iridium‐dispersed carbon paste enzyme electrodes
Electroanalysis, 1996AbstractAn highly selective first‐generation glucose biosensor, based on an iridium‐dispersed carbon‐paste transducer, is described. The iridium‐on‐carbon particles provide excellent electrocatalysis for both the reduction and oxidation of hydrogen peroxide.
