Due to their immunotoxicity, aflatoxins are considered as very important natural contaminants of a wide variety of agricultural products. Although conventional techniques such as high-performance liquid chromatography (HPLC) and gas chromatography (GC) combined with mass spectrometry (MS) have traditionally been used to detect such food contaminants, they are relatively expensive, laborious, and time consuming which limits their use for in field analysis at the so-called point-of-care (POC). Electrochemical biosensors are emerging devices that meet these expectations since they rely in reliable, simple, inexpensive, portable, selective, and easy-to-use analytical procedures and instruments that can be used by unskilled personnel outside the laboratory.
