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.

For this reason, it is mandatory to develop highly sensitive, reliable, rapid, and cost-effective sensing systems/devices such as electrochemical sensors/biosensors.

AbstractMicroelectrode arrays-based double electrode systems possess the property of diffusion layer overlapping between the two sets of electrodes. They have received increased attention in recent years in the field of electrochemistry and electroanalytical chemistry. This review introduces the fabrication, characterization, and applications of microelectrode arrays-based double electrode systems. The progress of photolithography enables and benefits microfabrication of the electrode systems with various geometries. As an essential step before electrochemical applications, various characterization methods are addressed to monitor the quality of the fabricated electrodes. Following that, applications as electrochemical sensors in generator-collector mode are discussed. Then, electrochemical sensors in bipolar mode, an interesting phenomenon existing in double electrode systems, are also introduced. Finally, applications of double electrode systems to the measurement of fundamentally electrochemical parameters are demonstrated.
