“…The product had stable structure and sensitive specific adsorption performance to EC, and the regression model showed good fitting effect. Kanyong et al 30 developed a graphene-based/molecularly imprinted carbon composite electrode (rGO/SPCE), Zhao et al 31 improved it to a disposable electrochemical biomimetic sensor for fast and selective detection of EC. The sensor specifically bound to EC quickly without sample pretreatment.…”

“…Before modification, SPCE was gently cleaned with 70 % ethanol followed by DI and dried under the flow of nitrogen to eliminate any dust that had accumulated on the electrode surface. After cleaning, 60 μL (1 mg mL −1 ) of GO dispersion was placed over the electrode surface, and electroreduction was performed using cyclic voltammetry, by scanning the potential in the range of 0 V to −1.8 V at a scan rate of 50 mV s −1 for 15 cycles to make ErGO/SPCE [34] . The Au/ErGO/SPCE was prepared by electro‐reduction of Au on ErGO/SPCE using a solution of 1 m m tetrachloroauric acid trihydrate in 0.1 m sulphuric acid, by cyclic voltammetry.…”

Herein, we report the electrochemical determination of roxarsone (ROX) on modified screen‐printed carbon electrodes (SPCE). Graphene oxide was reduced electrochemically on the working area of SPCE using cyclic voltammetry (CV) to form electrochemically reduced graphene oxide (ErGO), followed by electrochemical deposition of gold (Au) on ErGO/SPCE to get a final modified electrode Au/ErGO/SPCE. The modified electrode offered a significant surface area and improved electron transfer capability; hence it was used as an electrochemical sensor for the determination of ROX which is commonly used in meat production and poultry as a supplement to increase weight and improve feed efficiency. The effect of pH on the electrochemical behaviour of ROX on the Au/ErGO/SPCE was investigated by (CV) and square wave voltammetry (SWV). Under optimum experimental conditions, the linear calibration range, the limit of detection (LOD), and quantification (LOQ) were found to be 1 μmol L−1–1000 μmol L−1, 14.4 nmol L−1, and 47.9 nmol L−1 respectively. The proposed electrochemical sensor was successfully applied to determine low concentrations of ROX in lab samples as well as in real meat (spiked) samples. Overall, a good recovery rate and accuracy were obtained, endorsing onsite use of the developed sensor for quick and accurate analysis.

“…Paper materials (Bhardwaj et al., 2020; Martin‐Yerga, 2019) have drawn considerable attention as electrochemical electrode substrates because of their simplicity, disposability, high cost‐effectiveness, and excellent biocompatibility. Although cellulose‐rich paper shows poor electrical properties and mechanical/chemical stability, researchers have developed advanced materials as electrode‐making materials to enhance stability, operational convenience, and electrochemical performance of paper‐based electrode substrates (Nantaphol et al., 2019; Zhao et al., 2017). Apart from paper‐based electrodes, inexpensive high‐performance polymer plastic materials such as polyethylene terephthalate (PET) with excellent stability were potential electrode substrates.…”

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.
