Elimination voltammetry with linear scan (EVLS) represents the fast and simple improvement of linear-sweep or cyclic voltammetric results. Through the various elimination functions, EVLS offers a new tool not also for better understanding of complex electrochemical processes on the surface of working electrodes, but also for improving the sensitivity of electrochemical measurements. The paper i...

Essential to the renewal of interest in polarography and voltammetry in the 1970s were the availability of reliable polarographs offering the pulse mode, with sensitivity down to lo-‘-lo-* M and h’gh 1 er resolving power; a better understanding of the electrode processes of compounds of pharmaceutical interest (active agents, excipients, additives, antioxidants, etc.); and the application of ox...

Aptasensors based on stripping voltammetry exhibit several advantages, such as high sensitivity and multi-target detection from stripping voltammetric technology, and high selectivity from the specific binding of apamers with targets. This review comprehensively discusses the recent accomplishments in signal amplification strategies based on nanomaterials, such as metal nanoparticles, semicondu...

This communication characterises the differential pulse voltammetric response of ultramicroelectrodes in connection with two different models.

“Cyclic voltammetry” is one of the most common electrochemical techniques, not only for electrochemists but also researchers in other fields. However, principles cyclic voltammetry are very complex; beginners and even experts may struggle with their application. Therefore, we explain fundamental Part 1 introduce practical issues associated recent trends such as fuel cells, capacitors, sensors 2...

The cobalt (Co(II)) ion is a main component of alloys and considered to be carcinogenic, especially due to the carcinogenic and toxicological effects in the aquatic environment. The toxic trace of the Co(II) detection was conducted using the infrared photodiode electrode (IPDE) using a working electrode, via the cyclic and square-wave anodic stripping voltammetry. The results indicated a sensit...

Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

Drug-associated cues have profound effects on an addict's emotional state and drug-seeking behavior. Although this influence must involve the motivational neural system that initiates and encodes the drug-seeking act, surprisingly little is known about the nature of such physiological events and their motivational consequences. Three experiments investigated the effect of a cocaine-predictive s...
