“…The detection of dissolved oxygen at the electrode prepared by the electrodeposition of an indigo tetrasulphonate (ITS) film onto a previously modified GCE electrode with cross-linked (via gluthaldehyde) poly-L-lysine was reported by Tsai et al [132]. The authors used this electrode in the rotation mode for voltammetric measurements.…”

The development of sensing coatings, as important sensor elements that integrate functionality, simplicity, chemical stability, and physical stability, has been shown to play a major role in electrochemical sensing system development trends. Simple and versatile assembling procedures and scalability make polyelectrolytes highly convenient for use in electrochemical sensing applications. Polyelectrolytes are mainly used in electrochemical sensor architectures for entrapping (incorporation, immobilization, etc.) various materials into sensing layers. These materials can often increase sensitivity, selectivity, and electronic communications with the electrode substrate, and they can mediate electron transfer between an analyte and transducer. Analytical performance can be significantly improved by the synergistic effect of materials (sensing material, transducer, and mediator) present in these composites. As most reported methods for the preparation of polyelectrolyte-based sensing layers are layer-by-layer and casting/coating methods, this review focuses on the use of the latter methods in the development of electrochemical sensors within the last decade. In contrast to many reviews related to electrochemical sensors that feature polyelectrolytes, this review is focused on architectures of sensing layers and the role of polyelectrolytes in the development of sensing systems. Additionally, the role of polyelectrolytes in the preparation and modification of various nanoparticles, nanoprobes, reporter probes, nanobeads, etc. that are used in electrochemical sensing systems is also reviewed.

“…Electrochemical methods are now emerging as powerful and versatile analytical techniques and have found vast applications in many important fields including pharmaceutical industry, and biological and environmental applications (Farghaly et al, 2014;Tsai et al, 2011;Sivasubramanian and Sangaranarayanan, 2011;Beitollahi et al, 2008). The use of electro analysis is increasing day by day due to high sensitivity, reduction in solvent and sample consumption, high-speed and low operating cost (Almeida et al, 2013;Halls et al, 2013;Yuzhi Li et al, 2013;Cheng et al, 2012;Aaboubi and Housni, 2012;Farghaly and Ghandour, 2005).…”

Quantitative studies of Cr(VI)- thymoquinone complex have been performed by cyclic voltammetry. For this purpose glassy carbon, platinum and saturated calomel electrodes were used as working, auxiliary and reference electrodes, respectively. The effects of concentrations and metal-ligand ratios on Cr(VI)- thymoquinone complex were investigated. Effect of concentration was found to follow Randles-Sevcik equation. Calibration curve method with linear regression line confirms that cyclic voltammetry can be used for quantification of Cr(VI)-thymoquinone complex for pharmaceutical assay. Complete complex formation seems to occur at metal ligand ratio 1:1. Results indicate quasi-reversible electron transfermechanism. E° and diffusion coefficient of complex at different concentrations and metal ligand ratios were also calculated and found to be 0.244±0.01 V and 3.45´10-5 cm2s-1, respectively. The values of transfer coefficients, a and b, were found to be 0.716±0.02-1.231±0.01 and 0.814±0.01-0.906±0.01, respectively.

“…The interest in developing electrochemical-sensing devices for use in environmental monitoring, clinical assays, and etc. Electrochemical sensors satisfy many of the requirements for such tasks, particularly owing to their inherent specificity, rapid response, sensitivity, and simplicity of preparation for the determination of organic molecules, including drugs and related molecules in pharmaceutical dosage forms and biological fluids [2,3]. Dopamine (DA) is an important neurotransmitter molecule of catecholamines and its deficiency leads to brain disorders, such as Parkinson's disease and schizophrenia [4][5][6].…”
