“…To enhance AFM 1 detection in milk, Kaur [40] and team innovatively integrated molybdenum disulfide (MoS2) quantum dots (QDs) with a zirconium-based metal-organic framework (UiO-66-NH2), resulting in a novel nanocomposite material. MoS2 quantum dots are known for their substantial theoretical capacity and robust electrochemical performance, whereas MOF is characterized by their high charge transfer resistance.…”

Mycotoxins, with their teratogenic, carcinogenic, and mutagenic effects, pose a significant threat to food safety, socio-economic development, and human health. They are commonly found in cereal crops at concentrations that are difficult to detect, necessitating rapid, sensitive, and accurate detection methods. Metal-Organic Framework (MOF) boasts advantages such as a high specific surface area, high porosity, tunable structures, good conductivity, and stability, making them widely used as excellent metallic materials. Recently, many have made progress in constructing electrochemical sensors based on MOF in combination with metal nanoparticles, porphyrins, polycyclic aromatic hydrocarbons, graphene, etc., for the detection of mycotoxins in food, achieving promising results. In this review, we discuss the harmful effects of mycotoxins, list the regulatory standards for mycotoxins in food set by different organizations and countries, and highlight the methods for detecting common mycotoxins in food using MOF-based electrochemical sensors, providing a reference for subsequent detection of mycotoxins in food.

Feeding the world’s increasing inhabitants requires considerable quantities of food, whose quality is essential to personal and economic health. Food quality parameters are mandatory to control throughout the fresh produce supply chain to meet consumer requests. Until now, different analytical techniques have been employed in food safety control. However, most of these are laboratory needed, expensive, and time-consuming. To address these obstacles, many researchers have concentrated on developing electrochemical sensors (ECSs) as a powerful method with great sensitivity and reliability for food evaluation. Metal-organic frameworks (MOFs) with surprisingly porous morphology provide uniform yet tunable features, a high specific surface, and established practical applications in various fields. MOF-based ECSs present novel routes for the fast and effective detection of food contaminants or nutrients. In this current review, we concentrate on the MOF-based ECSs for food evaluation by first overviewing the library of available MOF sensors from pristine to MOF-bio composites and then exploiting recent application fields, with an emphasis on how this novel material unlocks new opportunities to monitor food nutrients or hazards.

“…Moreover, Gurjeet Kaur et al (2022) [ 60 ] developed a MoS 2 QDs@UiO-66-NH2 sensor by introducing screen-printed carbon electrodes with a functional nanohybrid comprising a quantum dot (QDs) zirconium-based MOF and MoS 2 , namely, UiO-66-NH 2 . The modified MoS 2 /UiO-66 electrodes were coated with monoclonal antibodies specific to aflatoxin M1 (AFM1) and subsequently evaluated for electrochemical sensing of AFM1.…”

Mycotoxins in food are hazardous for animal and human health, resulting in food waste and exacerbating the critical global food security situation. In addition, they affect commerce, particularly the incomes of rural farmers. The grave consequences of these contaminants require a comprehensive strategy for their elimination to preserve consumer safety and regulatory compliance. Therefore, developing a policy framework and control strategy for these contaminants is essential to improve food safety. In this context, sensing approaches based on metal-organic frameworks (MOF) offer a unique tool for the quick and effective detection of pathogenic microorganisms, heavy metals, prohibited food additives, persistent organic pollutants (POPs), toxins, veterinary medications, and pesticide residues. This review focuses on the rapid screening of MOF-based sensors to examine food safety by describing the main features and characteristics of MOF-based nanocomposites. In addition, the main prospects of MOF-based sensors are highlighted in this paper. MOF-based sensing approaches can be advantageous for assessing food safety owing to their mobility, affordability, dependability, sensitivity, and stability. We believe this report will assist readers in comprehending the impacts of food jeopardy exposure, the implications on health, and the usage of metal-organic frameworks for detecting and sensing nourishment risks.
