Reports from Department of Chemistry Provide New Insights into Mycotoxins (Application of magnetic solid phase extraction for separation and determination of aflatoxins B-1 and B-2 in cereal products by high performance liquid ...)

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Biological Factors. According to news reporting out of Hamadan, Iran, by NewsRx editors, research stated, "A simple and sensitive method based on the magnetic solid phase extraction with modified magnetic nanoparticles followed by high performance liquid chromatography with fluorescence detection has been developed for extraction and determination of aflatoxins B-1 (AFB(1)) and B-2 (AFB(2)) in cereal products. Magnetic nanoparticle coated with 3-(trimethoxysilyl)-1-propanthiol (TMSPT) and modified with 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) was used as an antibody-free adsorbent."

Our news journalists obtained a quote from the research from the Department of Chemistry, "Under the optimal conditions, the calibration curves for AFB(1) and AFB(2) were linear in the ranges of 0.2-15 mu g L-1 and 0.04-3 mu g L-1, respectively. Detection limit was 0.041 mu g L-1 for AFB(1) and 0.013 mu g L-1 for AFB(2). The proposed method was successfully applied to the determination of AFB(1) and AFB(2) in spiked corn and rice samples with an average recovery of 93.5%."

According to the news editors, the research concluded: "The results demonstrated that the developed method is simple, rapid, inexpensive, accurate and remarkably free from interference effects."
