Carbon paste electrodes modified with enzymes, tissues, and cells

1995

View full text Add to dashboard Cite

A review is presented dealing with the use of carbon paste amperometric electrodes for electroanalytical purposes, with either the surface or the bulk being modified with biologically derived material such as enzymes, tissues, and cells. It covers virtually all the publications which have appeared from the very first enzyme-modified carbon paste electrode up to early 1994 and includes 220 references.

“…Possibility of CPE modification by various compounds eventually by extracts and homogenates is their excellent property and advantage [35,36,38]. The aim of such modification is to achieve maximal possible sensitivity and selectivity of the electrochemical measurement [46].…”

Zeptomole Detection of Streptavidin Using Carbon Paste Electrode and Square‐Wave Voltammetry

et al. 2007

We compared the suitability of avidin and streptavidin for avidin-biotin technology in view of the sensitivity of the analysis using square-wave voltammetry. We found out during our preliminary experiments that streptavidin gave approximately 100 times higher electrochemical response in comparison with avidin at the same experimental conditions and concentration. Thus, we used two approaches for streptavidin determination -analysis directly in electrochemical cell and analysis by adsorptive transfer technique (AdTS). Ten minutes long accumulation on carbon paste electrode surface was ascertained as optimal in both cases. Limits of detection were 0.3 aM (electrochemical cell) and 30 aM (AdTS).

“…They can be considered as universal solubilization media for both hydrophilic and hydrophobic analytes, thus allowing the enzymatic determination of compounds scarcely soluble in water. Wang et al fabricated laccase and tissue-based enzyme electrode to detect phenolic compounds in reversed micellar systems [23,24]. Pingarron et al immobilized HRP on the surface of a graphite electrode by direct adsorption and systematically studied the behavior of the HRP biosensor in micellar systems with regard to the composition of the emulsion, the nature of the organic solvent and of the surfactant [25].…”
