“…In most cases, the binding of affinity recognition receptors such as antibodies, Apt, and enzymes would block electron transfer on the electrode surface because of their natural insulation characteristic, thereby reducing signal response range and detection sensitivity. Advanced nanomaterials as electrode modifiers can effectively address poor conductivity caused by the binding of nonconducting receptors on the electrode, achieving highly sensitive and selective analysis (Albayrak et al., 2016; G. Shen et al., 2016; S. Wang et al., 2019). Notably, the blocking effect of receptors for electron transfer on the electrode surface can be utilized for designing electrochemical signal amplification strategies.…”

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.

Heavy metals and metalloid pollution poses a severe threat to the environment and human health. Various anthropogenic sources are responsible for the release of these contaminants into the water and food chain of humans and animals. To protect the environment and human health, the detection of heavy metals in various environmental matrices becomes vital. Sophisticated lab-based instruments require more time, effort, and huge investments which warrants the requirement of fieldbased disposable sensors. Various optical and electrochemical sensors are reported to demonstrate good sensitivity, selectivity, and detection limits (LOD). The disposable electrodes comprised of glass, paper, plastic, and fabric are gaining importance owing to the ease of application in field analysis, reproducibility, and low cost. The majority of these sensors are based on noble/precious metals namely gold, silver, and platinum. However, limited availability and high cost of these receptors restrict wide spread applicability of these sensors. Numerous earth-abundant materials and non-noble metalbased sensors are also evolving recently due to several advantages namely large-scale availability, ease of modifications, stability, and shelf life which overcomes the limitations of noble/precious metals-based sensors. The present review provides a review of recent advances in various non-noble and earth-abundant micro and nanomaterials used as receptors in optical and electrochemical biosensors for the detection of metals/metalloids in various matrices. The review also highlights the strategies for the design and fabrication of disposable electrodes, their modification methods, detection strategy, and mechanism involved in the detection of heavy metals. Various gaps existing in the reported sensor systems and future perspectives are also delineated in the present manuscript.
