Rapid Degradation of Aflatoxins by Treatment With Vacuum Ultraviolet Radiation Arising From Hydrogen Plasma

open access: yesPlasma Processes and Polymers, Volume 23, Issue 1, January 2026.
Intense VUV radiation ranging from 140 to 160 nm emitted by low‐pressure hydrogen radiofrequency plasma effectively decomposes a mixture of B1, G1, B2, and G2 aflatoxins on quartz glass substrates. Artificially contaminated maize grains with the same aflatoxin mixture resulted in 80% toxin removal in under 1 min. ABSTRACT A rapid, nonthermal method for

Confirmatory Tests for Aflatoxin B1

open access: yesJournal of AOAC INTERNATIONAL, 1964
Abstract Three confirmatory tests have been devised to identify aflatoxin B±. Portions of the isolated toxin are treated with formic acid-thionyl chloride, acetic acid-thionyl chloride, and trifluoroacetic acid, respectively, and aliquots of the three fluorescent reaction products are spotted on thin-layer chromatography plates ...

Aptamer based surface plasmon resonance sensor for aflatoxin B1

open access: yesMicrochimica Acta, 2017
The authors describe a surface plasmon resonance (SPR) based aptasensor for the carcinogenic mycotoxin aflatoxin B1 (AFB1) in a direct assay format. The aptamer is immobilized on the surface of a commercial sensor chip, and the SPR signal increases on ...

Assessing essential oils from Macaronesia: a study on their efficacy against phytopathogenic and obligate biotrophic fungi

open access: yesPest Management Science, Volume 82, Issue 1, Page 421-432, January 2026.
Essential oils (EOs) extracted from eight culinary herbs and spices were evaluated via direct‐contact bioassays, both in vitro and in vivo, against three species of phytopathogenic fungi and one obligatory biotrophic fungus. Phenylpropanoid‐rich EOs presented the strongest antifungal activity in both bioassays with the phytopathogenic and the obligate ...

Quantitative Analysis of Total Aflatoxins in Dairy Cattle Feed Using a Competitive Lateral Flow Immunoassay: A Regional Study in Tigray, Ethiopia

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Quantitative analysis of total aflatoxins in dairy cattle feed across five urban centres in Tigray, Ethiopia, revealed that 22.4% of samples exceeded national limits and 29.1% surpassed EU thresholds. Higher contamination levels were associated with roughage‐based feed, poor storage conditions and the presence of toxigenic Aspergillus flavus and A ...

Early detection of the aflatoxin B1 mutational fingerprint: A diagnostic tool for liver cancer

open access: yesMolecular & Cellular Oncology, 2017
Using duplex-consensus sequencing technology, we recently identified the characteristic high-resolution mutational spectrum of the liver carcinogen aflatoxin B1 in a mouse model, many months before aflatoxin-induced tumors are detectable.
