Cobalt(II)  complexes of isonicotinoyl hydrazones of two series of ligands have been synthesized and characterized on the basis of elemental analyses, molar conductance, magnetic moment, mass, IR, UV spectral data. Electrochemical behavior of ligands and complexes has been investigated by using cyclic voltammetry. Cyclic voltammetric studies reveal that the oxidation/reduct...

The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...

In recent years, new strategies for bacteria determination have been developed in order to achieve rapid detection and adequate limits of quantification microorganisms. This review classifies voltammetric sensors according whether the are directly or indirectly detected. Direct methods based on recognition themselves, either labeled label-free mode. contrast, indirect detect a metabolite produc...

Various carbon-based sensors (graphene, carbon nanotubes, graphite, pencil glassy carbon, etc.) have distinctive behavior and a broad range of importance for identifying sex hormones like estriol, estradiol, estrone, progesterone, testosterone. The current review emphasizes voltammetric, amperometric, electrochemical impedance spectroscopic methods detecting some these hormones. existence, stru...
