Electrochemical DNA-Based Biosensors as Useful Tools for Food Analysis

The presence of harmful chemicals and microorganisms in food is often addressed to food contamination, which can cause consumer illness at different levels of severity. Aptasensors can become a helpful tool in the detection of contaminants and allergens as a highly sensitive and easy-to-use analytical procedure. Moreover, the introduction of nanostructured systems allows the miniaturization and the portability of the devices, which make them suitable for on-field screening analysis. The aim of this manuscript is to give to readers an overview on the most recent important achievements of our research group in the realization of electrochemical aptasensors to be applied in food analysis.
