Abstract Electroanalytical and optical techniques are widely used in the development of nanomaterials-based sensor platforms. These have a quick response, high sensitivity, selectivity. nanomaterial-based sensors must be able to detect biomarkers, pathogens, toxins, pharmaceuticals biological matrices associated with cardiovascular disease, cancer, neurodegenerative diseases. Considering these ...

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.

Some mistakes in the paper published in the Journal of Electroanalytical Chemistry 528 (2002) 1 are corrected. The resistance changes of a PdjH electrode caused by the co-conduction of the electrolyte, the concentration-cell effect and collection of electrolysis current in the in situ resistance measurement using direct currents are calculated analytically. Some advice is given for resistance m...

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...
