“…GO, a 2D carbon nanomaterial, has an approximately 3 : 1 ratio of C to O and is widely used as a building block in electrochemical sensors and biosensors owing to its high specific surface area (SSA), similar structure to GR, large functional groups on its surface (e. g., hydroxyl, carboxyl, and epoxy groups), and high mechanical strength [4,27,73,101,102] . The oxygen‐containing functionalities of GO are responsible for its swelling in water and other solvents and for preventing restacking and agglomeration of GO′s carbon sheets.…”

“…The nonenzymatic sensor (Fc/APTMS/GO/GCE) exhibited reasonable selectivity, long‐term stability, and excellent electrocatalytic activity. The enhancement of peak current in every drop of CT in AMP detection arose due to Fc + production of Fc + through electrochemical oxidation of Fc, which oxidizes catechol to o ‐quinone [101] . Palanisamy and his group [23] fabricated a binary nanocomposite of GO and polymelamine (PM) to utilize the specific properties of both GO and PM for electrochemical sensing of CT.…”

Dihydroxybenzene is regarded as a serious environmental pollutant. Its detection through electrochemical methods is still challenging due to having a similar structure and overlapping signals with the conventional bare electrode. Thanks to the unique features and wide applicability of carbon nanotubes, graphene, and their derivatives, they can be used as modifiers to overcome the poor resolution ability of bare electrodes in the detection of dihydroxybenzene. This review focuses on the use of carbon nanotubes, graphene, and their derivatives and nanocomposites to enhance the electrocatalytic activity of conventional bare electrodes for dihydroxybenzene sensing. The reports from 2011–2020 on the simultaneous and/or individual detection of three different dihydroxybenzenes – hydroquinone, catechol, and resorcinol – are summarized. This review also highlights the challenges and prospects surrounding the sensitive and selective detection of dihydroxybenzene.

This study is on current developments concerning ferrocene (FC) and its derivatives on the basis of electrochemical biosensors and sensors. The distinct physiochemical characteristics of FC have enabled the development of new sensor devices, specifically electrochemical sensors. Several articles have focused on the implementation of FC as an electrode constituent while discussing its electrochemical behavior. Furthermore, typical FCdesign-based biosensors and sensors are considered as well as practical examples. The favorable design of FC-based biosensors and general sensors needs adequate control of their chemical and physical characteristics in addition to their surface immobilization and functionalization.

Role of the Supporting Electrolyte Ions and Additives on the Electron Transport Properties of Electrografted Films Bearing Ferrocenyl Moieties

The electrochemical oxidation of 6‐ferrocenylheptanoate was used to modify the surface of glassy carbon electrodes with thin films bearing ferrocene molecules. These films grow layer by layer and behave as surface redox catalyst during the electrografting. The electrografted films have a structure with pinholes or channels, whose existence was deduced from the redox behavior of the film in acetonitrile solution containing different supporting electrolytes and organic additives. The electron transport through this film requires the presence of the electrolyte anions in the film channels. However, the voltametric feature of the grafted films is sensitive to the electrolyte cation size. The supporting electrolyte anions inside the film channels stabilize the ferrocenium species during the film oxidation. However, the presence of the cations is required to keep the inner charge balance. The inclusion of both anions and cations inside the grafted film determines the surface coverage obtained from the voltammetric experiments.
