Safety and quality are key issues for the food industry. Consequently, there is growing demand to preserve the food chain and products against substances toxic, harmful to human health, such as contaminants, allergens, toxins, or pathogens. For this reason, it is mandatory to develop highly sensitive, reliable, rapid, and cost-effective sensing systems/devices, such as electrochemical sensors/biosensors. Generally, conventional techniques are limited by long analyses, expensive and complex procedures, and skilled personnel. Therefore, developing performant electrochemical biosensors can significantly support the screening of food chains and products. Here, we report some of the recent developments in this area and analyze the contributions produced by electrochemical biosensors in food screening and their challenges.

“…Pesticides are widely used, and when they are handled incorrectly, can be hazardous for human health and the environment. Velusamy et al [147] trapped cellulose microfibers into rGO and fabricated a sensor for the detection of fenitrothion organophosphorus pesticides. The interaction between the functional groups of cellulose and defects of rGO facilitated the transfer of electrons, which boosted the cyclic voltammetry (CV) signal of the analyte, improved the LOD of the sensor to 8 nmol L À 1 , and expanded the linear response range up to 1.134 mmol L À 1 .…”

Owing to their versatility and unique characteristics, graphene‐based materials have been used extensively for the development of electrochemical sensors and biosensors. The key to the maximum potential of these materials is the understanding of the role their structure plays in their modification processes. Herein, we summarize some structural characteristics of graphene oxide (GO) and reduced graphene oxide (rGO) and explore different surface modification methods for electrochemical sensing applications. surveyed the most recent applications of these materials as (bio)sensors, particularly for environmental monitoring and health‐related applications, such as quantification of biomarkers and metabolites and detection of cancer cells. The low detection limits, selectivity toward target molecules, and robustness of GO‐ and rGO‐based electrodes render them critical materials for the preparation of sensors for routine analysis and monitoring.
