For achieve sensitivity in lab-on-a-chip electrochemical detection, more reliable probing methods are required, especially for repeated measurements. Spring-probes are a promising candidate method which can replace needle-like probes and alligator clips that usually produce scratches on the surface of gold electrodes due to the strong physical contacts needed for electrochemical measurements. T...

This article provides an overview of solution-based methods for the controllable synthesis of metal oxides and their applications for electrochemical energy storage. Typical solution synthesis strategies are summarized and the detailed chemical reactions are elaborated for several common nanostructured transition metal oxides and their composites. The merits and demerits of these synthesis meth...

The phenomenon of corrosion in metallic materials such as 316 stainless steel (316SS), produce a degradation which is mainly represented by the lost of metallic properties. One way to study this phenomenon is analyzing microscope digital images of materials exposed to corrosive processes, and the analysis of electrochemical signals using electrochemical noise measurements. The traditional techn...

Magnetoelastic alloy films have been used as a working electrode in an electrochemical cell. This material allows magnetic interrogation of electrochemical deposition. This technique was used to monitor the electrochemical deposition of polypyrrole by multisweep (CV) and potentiostatic methods. Since the determination of the mass-sensitive magnetoelastic film's resonance frequency is based on m...

A bifunctional molecular linker containing both aryl diazonium and trioxolane groups was synthesised and its ability to sequentially functionalise glassy carbon and covalently immobilise heme investigated. Functionalisation was demonstrated by electrochemical techniques.

High throughput electrochemical techniques are widely applied in material discovery and optimization. For many applications, the most desirable electrochemical characterization requires a three-electrode cell under potentiostat control. In high throughput screening, a material library is explored by either employing an array of such cells, or rastering a single cell over the library. To attain ...

Electrochemical impedance spectroscopy has been adapted for systems containing large capacitances. For signal generation and recordi...

In this work, a nickel-modified glassy carbon electrode (GCE) was prepared using a potentiostatic method in 0.1 M acetate buffer solution at pH 4.0 containing 1.0 mM nickel nitrate. Nickel hydroxide nanoparticles were prepared using consecutive potential scanning in 0.1 M NaOH solution. The as-prepared catalyst was characterized by field emission scanning electron microscopy and electrochemical...

A novel strategy for electrochemical biosensing of food pathogenic bacteria using nanostructured electrochemical magneto electrode is reported. In this approach, the bacteria are attached to magnetic beads by immunological reaction with specific antibody against Salmonella. Further amplification of the genetic material with a double-tagging set of primer is then performed and the amplicon captu...
