A novel electrochemical sensor was proposed for the determination of amitriptyline based on the copper oxide (CuO) nanoparticles modified graphite screen-printed electrode. CuO nanoparticles were used to enhance the surface area of the electrode and then improve the sensitivity of the electrochemical sensor. Amitriptyline electrochemical response characteristics of the modified electrode in a p...

evanescent wave spectroscopy using thin optically transparent electrodes and multiple reflections allows unique observations of the electrochemical interphase since the region of solution sampled is typically 100 nm from the electrode in the visible spectral region. this technique is found to be highly sensitive to the presence of absorbing adsorbed species

In this paper, the effect of penicillin G drug as a green corrosion inhibitor on mild steel in 1.0 Mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The inhibition efficiencywas found to increase with increasing inhibitor concentration. Potentiodynamic polarizationmeasureme...

Electrochemical labeling of double-stranded (ds) DNA is achieved by redox-active DNA intercalators. Threading intercalators derived from naphthalenediimide appended with ferrocene reporter group in the side arms are particularly useful for this purpose. This allows a sensitive electrochemical detection of DNA hybridization on an array, providing a great potential for low-cost, high-throughput, ...

We report an electrochemical gating approach with ∼100% efficiency to tune the conductance of single-molecule 4,4'-bipyridine junctions using scanning-tunnelling-microscopy break junction technique. Density functional theory calculation suggests that electrochemical gating aligns molecular frontier orbitals relative to the electrode Fermi-level, switching the molecule from an off resonance stat...

A cheap and portable electrochemical immunosensor based on the silver-enhanced colloidal gold electrochemical stripping technique and gold nanoclusters (AuNCs) labels was proposed for the detection of human IgG. Inspired by adhesive proteins that secreted by marine mussels, the stable and robust film-poly (dopamine) was used to immobilize biomolecules (Ab1) on an indium tin oxide (ITO) electrod...

In this article, the structure and electrochemical performance of sodiated iron phosphate (FePO4) synthesized by the micro-emulsion technique have been investigated by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and electrochemical measurement. The results reveal that amorphous FePO4 could be transformed into crystallite sodium iron phosphate (NaFePO4) duri...
