Electrochemical aptasensing for the detection of mycotoxins in food commodities

The increasing demand for higher quality of wide-ranged food products lead to the overproduction of food commodities in an extremely short time. Such massive product output causes the demands on storage conditions, such as air humidity and regulation, time of storage, and temperature, to rapidly decrease. Therefore, a large variety of pathogenic microbes can be present in food commodities that can trigger a set of serious long-term health issues for human and animal beings. Nowadays, food contamination represents one of the most important worldwide issues that need to be regulated. Among all analytical methods, electrochemical aptasensors have shown to be great candidates for the fast, reliable, and ultrasensitive detection of foodborne pathogens, mainly mycotoxins, in food matrices. This work offers a complex overview of electrochemical aptasensors and their applications in food quality control. It includes modern immobilization strategies in combination with modern electroanalytical methods as detection techniques. This work presents the possibilities to create more practical and effective aptasensing devices with a high level of sensitivity, selectivity, and specificity. These innovations are brought out with a hope to be later involved in the development of miniaturized, portable, and commercially available lab-on-chip devices that would be applicable in a friendly manner for end-users.
