The past decade has seen an increasing number of extensive studies devoted to the exploitation of ordered mesoporous carbon (OMC) materials in electrochemistry, notably in the fields of energy and sensing. The present review summarizes the recent achievements made in field of electroanalysis using electrodes modified with such nanomaterials. On the basis of comprehensive tables, the interest in...

A novel potentiometric solid-state reference electrode containing single-walled carbon nanotubes as the transducer layer between a polyacrylate membrane and the conductor is reported here. Single-walled carbon nanotubes act as an efficient transducer of the constant potentiometric signal originating from the reference membrane containing the Ag/AgCl/Cl(-) ions system, and they are needed to obt...

Even though significant progress has been made in the development of electrodes for the in vivo detection of catecholamines, oxygen, and various cations, there has been little research on the feasibility of continuously monitoring drugs in whole blood by electrochemical sensing devices. Electroanalytical problems associated with the development of such electrochemical transducers include the ne...

A novel ion selective PVC membrane electrode for determination of propranolol is developed. Silicotungstic acid is used as the counter ion and diisononyl phthalate (DNP) used as the plastizer. The electrode exhibits excellent potential response properties, showing a Nernstian response in the concentration of 3.0 × 10–6 ~ 2.6 × 10–2 M with the slope of 54.7 mV per decade, shorter conditioning ti...

A light-addressable potentiometric sensor (LAPS) is a semiconductor-based chemical sensor, in which the measurement area defined by probe light illuminating plate. In this study, novel method to detect hydrogen permeation through metal was proposed using system, LAPS combined with micro-volume cell. The sensing surface of placed vicinity exit an iron sheet form cell filled Na2HPO4 solution, and...

Abstract The detection of hazardous carcinogenic heavy metals in aqueous solutions is important for biological health and environmental protection. There are various techniques to ascertain these oncogenic chemicals an solution, like a potentiometric electrochemical sensor, spectrophotometer colorimeter chemical sensors. As compared other available methods, the sensor has advantages such as low...
