Amperometric enzyme biosensors: Past, present and future

Electrochemical Methods for Total Antioxidant Capacity and its Main Contributors Determination: A review

“…In amperometry, the current generated at constant potential by the oxidation/reduction of the electroactive analysed compound, can be stoichiometrically correlated to the concentration of the latter [119][120][121]. It has been confirmed that the performances of the amperometric method with respect to sensitivity are subject to the chosen working electrode type, as well as to the potential value applied [85].…”

“…So in this case, amperometry benefits both the specificity imparted by the biocatalyst and the accuracy and rapidity of the electrochemical detection system, at the optimized potential value [119][120][121][122].…”

Future Applications of Electronic-Nose Technologies in Healthcare and Biomedicine

“…Yoo & Lee (2010) recently reviewed the present status and use of glucose biosensors in the management of diabetes in clinical practice. Dzyadevych et al (2008) discussed the advantages and disadvantages of amperometric enzyme biosensors for medical diagnostics and other potential healthcare applications. Gomila et al (2006) described some advances in the development of methods and techniques for the production, mobilization, electrical characterization, and development of olfactory nanobiosensors.…”

ZnO nanostructures in enzyme biosensors

“…A biosensor is an analytical device consisting of a biomatrix (e.g., enzymes, antibodies, nucleic acids, receptors, organelles, microorganisms) and transducer (e.g., electrochemical, photometric, acoustic/mechanical, piezoelectric, calorimetric), which converts biological information into measurable signals [1][2][3]. Enzyme biosensors in particular have attracted much attention [4].…”
