Voltammetric properties of electrodes made of multiple-walled carbon nanotubes (MWNTs) with different diameters were investigated by cyclic voltammetry. The results indicate that electrodes made of smaller MWNTs exhibit better voltammetric properties. In addition, electrodes made of mixed MWNTs with large diameter distribution possess the best voltammetric properties. The phenomenon can be expl...

Pseudomonas Aeruginosa (P. Aeruginosa) is a prevalent and opportunistic bacterium which frequently causes severe nosocomial infection. Current clinical detection methods are limited in terms of necessary time equipment. Increasingly, P. Aeruginosa’s electrochemically active virulence factor pyocyanin has facilitated its rapid detection, primarily through voltammetric such as cyclic voltammetry ...

The laser-induced modification of polyimide substrates to yield conductive graphitised tracks sensitive the solution pH is investigated. influence laser output and operating characteristics on surface morphology consequential impact electrochemical properties have been evaluated. Several sensor formats pursued using both potentiometric voltammetric methodologies found provide a stable means det...

The present study describes the use of a new carbon paste electrode modified by means of Silica nanoparticles prepared by a simple and rapid procedure for the determination of sodium diclofenac (DCF). Moreover, the present study focuses on the characterization of electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM) of the prepared Silica NPs-CPE. In this work, The...

Cobalt phthalocyanine (CoPC) compounds have been reported to provide electrocatalytic performances towards a substantial number of analytes. In these configurations, electrodes are typically constructed via drop casting the CoPC onto a supporting electrode substrate, while in other cases the CoPC complex is incorporated within the ink of a screen-printed sensor, providing a one-shot economical ...
