Potentiometric stripping analysis (PSA), also known as stripping chronopotentiometry (SCP), is an electroanalytical technique based on the accumulation either by electrolysis or by adsorption of the analyte on the electrode and its further stripping

The complex molybdoenzyme xanthine oxidase (XO) catalyses the oxidation of xanthine to uric acid. Here we report the first direct (unmediated) catalytic electrochemistry of the enzyme in the presence of xanthine. The only non-turnover response (witho

A finite difference method for simulating voltammograms of electrochemically driven enzyme catalysis is presented. The method enables any enzyme mechanism to be simulated. The finite difference equations can be represented as a matrix equation contai

The reversible formal potentials \(E_{\rm f}^0 \) of auracyanin A and auracyanin B, two closely related "blue" copper proteins from the photosynthetic bacterium Chloroflexus aurantiacus, have been determined by protein film voltammetry in the range 4

The voltammetry of solid 7,7,8,8-tetracyanoquinodimethane (TCNQ) and tetrathiafulvalene (ITF) at an electrode-microparticle-aqueous (electrolyte) interface generates characteristic current-potential profiles associated with solid-solid-phase transfor

The theory for the ‘total’ ac voltammogram of a surface bound molecule is presented as well as the theory for the dc component and ac harmonics. The theory has been verified by comparing theoretical dc component and ac harmonic voltammograms to t

Dynamic resistance compensated cyclic voltammograms have been obtained when solid tetrathiafulvalene (TTF) is converted to a highly conducting TTF+ salt. Two resistance transitions were detected, one being related to bulk transformation of solid by n

Catalytic reductive dehalogenation of hexachloroethane (HCE) was shown to be possible using a graphite electrode coated with a film of the poly(ester sulfonic acid) containing myoglobin (Mb). The effectiveness of the dehalogenation was limited by the

The theory of cyclic voltammetry of redox adsorbates based on the nonadiabatic kinetic models of Levich and Dogonadze (GMLD kinetics) is re-examined. It is shown that if generalized predictions of cyclic voltammetric behavior are sought, the model is
