Monoclonal antibody-quantum dots CdTe conjugate-based fluoroimmunoassay for the determination of aflatoxin B1 in peanuts

A fluoroimmunoassay towards aflatoxin B1 (AFB1) was presented using quantum dots as the fluorescent label. The CdTe QDs were successfully linked to the monoclonal antibody against AFB1. Based on the conjugated complexes, a novel direct competitive fluorescence-linked immunosorbent assay (cFLISA) was developed for AFB1 detection. The 50% inhibition value (IC50) of the cFLISA was 0.149 […]

Effect of ozone on aflatoxins detoxification and nutritional quality of peanuts

Aflatoxins are a group of secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus with carcinogenicity, teratogenicity, and mutagenicity. Aflatoxins may be found in a wide range of agri-products, especially in grains, oilseeds, corns, and peanuts. In this study, the conditions for detoxifying peanuts by ozonation were optimized. Aflatoxins in peanuts at moisture content of […]
