Broad-specificity photoelectrochemical immunoassay for the simultaneous detection of ochratoxin A, ochratoxin B and ochratoxin C

Biosensors and Bioelectronics, 2018
A broad-specific photoelectrochemical (PEC) immunosensor was developed for the simultaneous detection of ochratoxin A, ochratoxin B and ochratoxin C (OTA, OTB, OTC) by using the direct growth of CdS nanorods on FTO as the photoelectrode and Au nanoflowers-modified glass carbon electrode (GCE) as the bioelectrode.

Ochratoxins: A global perspective

Mycopathologia, 2006
Ochratoxins have been overshadowed by better-known mycotoxins, but they are gaining importance. Here we consider ochratoxins in the context of aflatoxins, which are better understood than ochratoxins on many levels. We review recent work on taxonomic distribution, contamination of commodities, biosynthesis, toxicity and regulatory aspects of ...

A nanozyme-based cascade colorimetric aptasensor for amplified detection of ochratoxin A.

Nanoscale, 2019
Colorimetric assays have been widely developed for the detection of toxin ochratoxin A (OTA), but most of them suffer from moderate sensitivity when they are adopted for the detection of trace OTA in a complicated food matrix.

Urinary ochratoxin A and ochratoxin alpha in pregnant women

Food and Chemical Toxicology, 2012
This study determined exposure of pregnant women to ochratoxin A (OTA). Forty samples of first-void urine samples from Croatian women in the third trimester of pregnancy were analyzed for OTA and its major metabolite ochratoxin alpha (OTα). The subjects filled a short food frequency questionnaire (FFQ).

Immunotoxic activity of ochratoxin A

Journal of Veterinary Pharmacology and Therapeutics, 2006
Ochratoxin A (OTA) is an immunosuppressant fungal compound, produced by toxigenic species ofAspergillusandPenicilliumfungi in a wide variety of climates and geographical regions. The contamination of food by this mycotoxin takes place primarily during preharvest periods. Almost all types of food can be contaminated.
