Immunomagnetic ochratoxin A assay with smartphone-based amperometric detection
- Toxic secondary metabolites produced by fungi (aka mycotoxins) are often identified as contaminants in food and pose a severe health risk. Ochratoxin A (OTA) is one of the most abundant mycotoxins found in grains such as wheat, rye or oats. Thus, the fast and cost-effective detection of OTA is of great importance, to ensure that the toxin concentration is below the legal limits. Currently, mycotoxin detection in mill operations is typically performed by means of the antibody-based ELISA (Enzyme-linked Immunosorbent Assay) method, which requires extensive laboratory equipment and specialized personnel. The aim of this project is to establish a more user-friendly detection method. Thus, we developed a magnetic bead-based assay enabling the quantification of OTA with a miniaturized potentiostat connected to a smartphone.
