Ochratoxin A (OTA) is one of the most important mycotoxin contaminants of foods, particularly cereals and cereal products, with strict low regulatory levels (of ppb) in many countries worldwide. An… Continue Reading
We report a direct competitive immunosensor for the rapid determination of ochratoxin A (OTA) in wine samples. Magnetic beads (1 ± 0.5 μm diameter) covered with streptavidin were functionalized with… Continue Reading
Competitive electrochemical immunosensors, based on disposable screen-printed electrodes (SPCEs), have been developed for the determination of the mycotoxin ochratoxin A (OTA). Two indirect… Continue Reading
A piezoelectric immunosensor was tested for ochratoxin A (OTA) mycotoxin detection through the immobilization of OTA–bovine serum albumin (OTA–BSA) conjugate on gold-coated quartz crystals (AT-cut/5… Continue Reading
An automatic solid-phase extraction (SPE) system coupled with a fluorescence detector was developed for the sensitive determination of Ochratoxin A (OTA) in wheat at the ng mL−1 levels. Cross-linked… Continue Reading
We report a sensitive electrochemical immunosensor for Ochratoxin A (OTA), which is a frequent mycotoxin contaminant in cereals and other kinds of agricultural commodities, based on a biotinylated… Continue Reading
