In this study, a low‐cost, disposable, sensitive and selective electrochemical sensor was developed for glucose determination, which is based on a pencil graphite electrode (PGE) modified with nickel hydroxide. Cyclic voltammetry was used to deposit nickel on PGE. The morphology and composition of the unmodified and modified PGE electrodes were characterized by field‐emission scanning electron microscopy (FE‐SEM), atomic force microscopy (AFM) and energy‐dispersive X‐ray spectroscopy (EDX). The performance of the as modified electrode towards the electrooxidation of glucose in alkaline media was evaluated with cyclic voltammetry and amperometry techniques. A linear relationship between the concentration of glucose and oxidation peak currents was observed in two concentration ranges of 0.004–3.5 mM and 3.5–9.0 mM. The detection limit was 2 μM at signal‐to‐noise ratio of 3. In addition to a fast response time (<2 s), the proposed sensor preserved 93 % of its original response towards glucose after 28 days. Also, the sensor showed a good reproducibility and high selectivity for glucose oxidation in the presence of common interfering species. The use of Ni(OH)2/PGE sensor was successfully tested in the determination of glucose in human blood serum for the first time in the literature.

“…MIPs show great advantage in food safety analysis because of their good ability to absorb and separate analytes from food samples (Shahtaheri et al., 2017). Electrochemical sensors based on MIP have been reported for the sensitive and selective determination of various food safety hazards such as pesticides, for example, dichlorodiphenyltrichloroethane (Miao et al., 2020), cypermethrin (D. Song et al., 2019), omethoate (Shi et al., 2016), diazinon (Motaharian et al., 2016), and 2,4‐dichlorophenol (Motaharian et al., 2016); veterinary drugs, for example, carbofuran (Amatatongchai et al., 2018, 2020), semicarbazide (W. Yu et al., 2020), ampicillin (Z. Liu et al., 2020), sulfadimidine (X. Wei et al., 2018), kanamycin (Bi et al., 2020), and lomefloxacin (J. Li et al., 2020); artificial additives, for example, sunset yellow (Arvand et al., 2017; Yin et al., 2018), melamine (S. Xu et al., 2018), and Sudan II (Rezaei et al., 2016); environmental contaminants, for example, estradiol (Q. Han et al., 2016; Xin et al., 2019), p ‐nonylphenol (M. Yu et al., 2019; Zheng et al., 2018), and triclosan (Zheng et al., 2018); natural toxins, for example, fumonisin B1 (Munawar et al., 2020), patulin (Hatamluyi et al., 2020), zearalenone (Radi et al., 2020), and ochratoxin A (Pacheco et al., 2015); and processing and package contaminants, for example, histamine (Mahmoud et al., 2020) and acrylamide (Mahmoud et al., 2020).…”

Food safety as a public health issue has aroused worldwide concern. Food safety risks caused by the existence of food safety hazards in food may occur in all stages of the food supply chain. Thus, great emphasis is placed on sensitive, selective, and convenient analytical methods of various food safety hazards in food. At present, nanomaterials are at the forefront of various electrochemical sensing applications. Given their unique physical, chemical, and biological characteristics, nanomaterials are considered perfect candidates for the design of electrode surface to construct electrochemical sensors with excellent analytical performance. With the assistance of nanomaterials, electrochemical sensors are a potential alternative to conventional methods of food safety analysis. This review focuses on current research achievements of nanomaterial‐assisted electrochemical sensors for food safety analysis reported in recent 5 years. It highlights the different detection mechanisms for analytes, flexible sensing strategies based on nanomaterials, and portable miniaturized electrochemical devices. Finally, the challenges and limitations in the design of electrochemical sensors for food safety analysis are also discussed.
