This review summarizes some recent developments in the fabrication of modified sensors and biosensors using carbon-based materials. The great potential electrodes as sensing platforms is exciting due to their unique electrical chemical properties, high accessibility biocompatibility. Carbon-based materials are particularly interesting almost infinite possibility functionalization with a wide va...

The ligand potassium hydrotris(N- (2,6-xylyl)-2-thioimidazolyl)borate (KTtxylyl) was utilized to construct a carbon paste modified electrode (KTtxylyl/CPE), which studied using electrochemical impedance spectroscopy, cyclic voltammetry and square wave (SWV). Its response investigated, it demonstrated significant improvement in the detection of both lead(II) cadmium(II), allowing determination a...

Cysteine forms self-assembled monolayers over gold nanoparticles. Based on this knowledge, a novel electrochemical sensor (Au-Au(nano)-Cys-SDS) has been constructed by the formation of self-assembly monolayer (SAM) of cysteine on gold-nanoparticles modified gold electrode (Au-Au(nano)-Cys) to be utilized for determination of dopamine in the presence of sodium dodecyl sulfate (SDS). Electrochemi...

The nitrofurazone (NF) electrochemical reduction has been studied by cyclic voltammetry (CV) and square wave (SWV) in non-aqueous medium using three different ionic liquids (IL): BMImTf2N, BMImBF4 BMMImTf2N, having a carbon fiber microelectrode as working electrode. In all of them, two reversible cathodic peaks were recorded for NF. Under higher frequency values, only one peak was registered. s...

In the present work, resolution and quantification of mixtures different opiate compounds in presence common cutting agents using an electronic tongue (ET) is evaluated. More specifically, ternary heroin, morphine codeine were resolved caffeine paracetamol. To this aim, array three carbon screen-printed electrodes modified with ink-like solutions graphite, cobalt (II) phthalocyanine palladium, ...
