This aim of this paper is to expound the complexity of thiol redox systems in the endoplasmic reticulum of eukaryotic cells to the electroanalytical community. A summary of the state of the art in electrochemical methods for detection of thiols gives an insight into the challenges that need to be addressed to bridge the disparity between current analytical techniques and applications in a 'real...

Microbial fuel cells (MFCs) represent a clean and renewable energy resource. To date, power generation in MFCs is severely limited. In order to improve performance, a wide range of techniques have been utilised for a fundamental scientific understanding of the components and processes and also to investigate MFC performance bottlenecks. In this tutorial review, we discuss the electrochemical/el...

The electrochemical detection of NADH is of considerable interest because it is required as a cofactor in a large number of dehydrogenase-based biosensors. However, the presence of oxygenated functionalities on the electrode often causes fouling due to the adsorption of the oxidised form, NAD(+). Here we report an electroanalytical NADH sensor based on DMF-exfoliated graphene. The latter is sho...

We explore the endeavours directed to development of electrochemical-based sensors for determination capsaicin and related compounds, starting from their use in hyphenated laboratory set-ups modern as stand-alone electroanalytical sensors.

b An electroanalytical method for studying electrode reactions, called cyclic chronopotenticmetry, in which the applied current is successively reversed a t each t,*ansition, is proposed. A circuit for carrying out automatic current reversals is described. T h e equations for the successive transition times for linear diffusion in a singie clmponent system have been derived and solved, and t h ...

The electroanalytical techniques of pulse polarography, stripping voltammetry and on-line electrochemical detection have been used for the identification and determination of trace concentrations of a wide variety of environmentally significant organic molecules, usually after the application of sample pretreatment procedures, certain separation techniques and, in some cases, derivatisation. Cl...

Approach • Study the kinetics of fuel cell electrode reactions on well-characterized model electrodes and high surface area fuel cell electrocatalysts using modern electroanalytical methods. • Study the mechanisms of the reactions using state-of-the art in-situ spectroscopes. • Use ultrahigh vacuum (UHV) methods of surface preparation and surface analyses to form tailored surfaces. • Synthesize...

A flow injection square wave cathodic stripping voltammetric method has been developed for the determination of sertraline in a pharmaceutical preparation. The method shows linearity between peak current intensity and sertraline concentration for the interval between 0.20 x 10(-6) and 1.20 x 10(-6) mol L(-1). Limits of detection and quantification were found to be 1.5 x 10(-7) and 5.0 x 10 (-7)...
