In order to develop a robust biosensor based on quartz crystal microbalance technique for antigen detection, a control of the steps of the surface functionalization has been performed by impedance spectroscopy. The gold electrode is functionalized with the self-assembled monolayer technique. The high insulating properties of the acidic thiol monolayer has been characterized with cyclic voltamme...

A three electrodes planar electrochemical sensor, based on CuO nanowires growth “in situ” on Cu working electrode, was fabricated by a simple micromachining technique and employed for the non-enzymatic determination of glucose. The microstructural and morphological characteristics of the modified electrode was investigated by XRD and SEM analysis. Cyclic voltammetry and chronoamperometric measu...

Fast-scan cyclic voltammetry (FSCV) is an electrochemical technique that utilizes the oxidation and/or reduction of an analyte of interest to infer rapid changes in concentrations. In order to calibrate the resulting oxidative or reductive current, known concentrations of an analyte must be introduced under controlled settings. Here, I describe a simple and cost-effective method, using a Petri ...

The redox behavior for bulk and nano silver nitrate (NSN) were studied by cyclic voltammetry technique in absence and presence of cefdinir antibiotic (CFD) using glassy carbon electrode (GCE) in 0.1 M KNO3 as supporting electrolyte at two different temperatures. Scan rates were studied for the redox reactions of bulk and nano silver nitrate (NSN) in absence and presence of cefdinir antibiotic (...

In this study, the protocol for arsenic (III) detection from an aqueous solution using stripping voltammetry on a silver-modified synthetic zeolite-carbonnanotubes-epoxy composite electrode (CNT-AgSZ) was elaborated. Three types of electrochemical techniques were used in order to optimize the operating conditions, i.e., cyclic voltammetry, differential-pulsed voltammetry and squarewave voltamme...

In this work, a simple and sensitive electrochemical method was developed to determine Sudan I by cyclic voltammetry and differential pulse voltammetry using a glassy carbon electrode modified with a chitosan/carbon nanotube composite. In cyclic voltammetry, Sudan I exhibited a well-defined oxidation peak located at 0.72 V at the multi-walled carbon nanotube (MWCNT)/chitosan-modified GCE. The d...

diolefinic antibacterial laser dye namely 1,4-bis[2-(4-pyridyl) vinyl] benzene (4pvb)have been investigated electrochemically using cyclic voltammetry, chronoamperometry, convolution and deconvolution voltammetry combined with digital simulation techniques at a platinum electrode in 0.1 mol / l tetra butyl ammonium perchlorate (tbap) in  solvent 1,2-dichloroethane.  the diolefinic species were ...
