Herein we describe the development, characterization and application of an electrochemical sensor based on the use of Nafion/MWCNT-modified screen-printed carbon electrodes (SPCEs) for the voltammetric detection of the anti-tuberculosis (anti-TB) drug ethambutol (ETB). The electrochemical behaviour of the drug at the surface of the developed Nafion/MWCNT-SPCEs was studied through cyclic voltamm...

In this work, different electrodes were employed for the determination of Cr(VI) by cathodic square-wave voltammetry (SWV) technique and adsorptive stripping (SWAdSV) in combination with diethylenetriaminepentaacetic acid. Using SWV, a comparison analytical performance bare glassy carbon electrode (GCE), ex situ (antimony-film—SbFE, copper-film—CuFE, bismuth-film—BiFE), GCE modified new magneti...

We hereby present an electrochemical approach for monitoring the three protein kinases sarcoma-related kinase (Src), extracellular signal-regulated kinase 1 (Erk1), and cyclin A-dependent kinase 2 (CDK2/cyclin A). The electrochemical sensor is based on the ability of kinases to transfer a redox-labeled phosphoryl group to surface-bound peptides that are highly specific substrates for the partic...

Hepatic oval cells (HOCs) are considered the progeny of the intrahepatic stem cells that are found in a small population in the liver after hepatocyte proliferation is inhibited. Due to their small number, isolation and capture of these cells constitute a challenging task for immunosensor technology. This work describes the development of a 3D-printed continuous flow system and exploits disposa...

In this report the thermochemical conversion of Sm2O3 to SmCl3 using AlCl3 in LiCl-KCl melt at 773 K is discussed. The final product was a mixture SmCl3, Al2O3, unreacted and chloride melt. electrochemical attributes analyzed with cyclic voltammetry (CV) square wave (SWV). crystallographic phases were studied X-ray diffraction (XRD) technique. major chemical optimized by varying effective param...

Cyclic voltammetry and square wave voltammetry have been used to investigate the transfer of highly hydrophilic ions, including anions and cations, by a simple two polarized interfaces setup. The expression of apparent half-wave potential has been established detailedly by virtue of theory of sampled-current voltammetry involving semi-infinite linear diffusion, which indicates that the property...

A glassy carbon electrode modified with a coating of polypyrrole (Ppy) exhibited an attractive performance for the detection and determination of a non-steroidal and non-narcotic analgesic compound, ketorolac tromethamine (KT). Cyclic voltammetry, differential pulse and square wave voltammetry were used in a combined way to identify the electrochemical characteristics and to optimize the condit...
