“…The chemically modified carbon paste electrodes find extensive application as sensors in the determination of drugs present in the biological systems at very low concentrations [45–49]. Further, they are also widely used as potentiometric sensors to detect the different heavy metal ions present in parts per million levels [50].…”

This environmentally benign work describes a simple electrochemical sensor constructed with a chemically modified carbon paste electrode (CMCPE) using aloe vera xanthate nanoparticles to detect mercury ions. The characterization and morphology of nanoparticles were thoroughly investigated using modern techniques. The CMCPE efficiently senses the mercury ions. The limit of detection of mercury ions wasexcellent to the order of 0.231 μg mL−1. Real‐time sample analysis showed promising results. The recovery range was between 99.4 % and 101.7 %. The activity of CMCPE was commendable even after fifty days.

“…It is worth to mention that a small cathodic peak (c 2 ) was observed at −0.8 V due to water reduction [45] . The effect of scan rates on cyclic voltammograms of Gr−W were studied to get details about the electrode reactions whether it is a surface controlled or diffusion controlled process [46] . CVs were recorded at different scan rates (from 0.01 to 0.2 V/s) in 0.1 M PBS using a Gr−W/GCE ( Figure 5B ) .…”

Reduced form of β‐nicotinamide adenine dinucleotide (NADH) and its oxidized form (NAD+) are the main cofactors involved in more than 300 dehydrogenase reactions. NAD+ is one of the important oxidizing agent for the oxidation of alcohol, aldehyde and ketones. Similarly, NADH has been used for the treatment of Alzheimer and Parkinson's diseases. Herein, we have reported synthesis of graphene flakes by electrochemical exfoliation of graphite in sodium tungstate solution. It was found that tungstate (WO42−) and hydroxyl (OH−) ions were intercalated into graphite layers and enabled the production of graphene flakes. As‐obtained graphene flakes were characterized by UV‐Visible (UV‐Vis), Fourier transform infrared (FT‐IR), Raman, Field emission scanning electron microscopy (FE‐SEM), Energy dispersive X‐ray (EDX) and High‐resolution transmission electron microscopies (HR‐TEM). FT‐IR, Raman and EDX analysis were confirmed that tungstate (WO42−) ions were present on the surface of graphene flakes. Moreover, graphene‐WO42− (Gr−W) dispersion was prepared by probe‐sonication to form a thin‐film on the surface of glassy carbon electrode (Gr−W/GCE). Interestingly, Gr‐W modified GCE reduced the overpotentials of NADH oxidation and NAD+ reduction. This new senor was also showed linear responses for NADH and NAD+ from 10–270 μM and 100–500 μM, respectively. Furthermore, the selectivity of the Gr−W/GCE was tested in the presence of L‐tyrosine, L‐isoleucine, L‐alanine, glutathione, dopamine (DA), ascorbic acid (AA), uric acid (UA), oxalic acid (OA), glucose, hydrogen peroxide (H2O2), acetaminophen (PA), potassium chloride (KCl) and sodium chloride (NaCl). It was found that selective detection of both NADH and NAD+ could be achieved by using Gr−W/GCE. Finally, the real application of the sensor was demonstrated by accurately detecting spiked NADH concentrations in human blood serum. The recovery analysis was also confirmed that Gr−W/GCE could be useful to detect NADH in biological samples.

The development of carbon paste electrodes in the 1970s generated considerable interest in the scientific community, because they offered several advantages over conventional membrane electrodes. At the beginning of the new millennium, the use of carbon nanomaterials as a new trend in their development gave additional impetus. After CPEs were successfully developed for potentiometric determination of more than 70 chemical elements, these electrodes gained additional interest for pharmaceutical and medical applications. This paper reviews the scientific literature of the last decade related to the development of CPEs for the quantitative determination of active pharmaceutical ingredients and their application in real samples.
