Journal ArticleDOI
Chemiluminescence competitive aptamer assay for the detection of aflatoxin B1 in corn samples
Won-Bo Shim,Won-Bo Shim,Hyoyoung Mun,Hyo-Arm Joung,Jack Appiah Ofori,Duck-Hwa Chung,Min-Gon Kim +6 more
TL;DR: In this article, a chemiluminescence competitive aptamer was developed for AFB1 using a hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme (HRP-DNAzyme) linked with an aptamer specific to AFB1.
Journal Article
Development of immunochromatography strip-test using nanocolloidal gold-antibody probe for the rapid detection of aflatoxin B1 in grain and feed samples
Won-Bo Shim,Zheng You Yang,Jung Sook Kim,Ji-Young Kim,Sung Jo Kang,Gun Jo Woo,Young Chul Chung,Sergei A. Eremin,Duck-Hwa Chung +8 more
TL;DR: The results indicated that the ICG strip test has a potential use as a rapid and cost-effective screening tool for the determination of AFB1 in real samples and could be applied to the preliminary screening of mycotoxin in food and agricultural products, generating results within 15 min without complicated steps.
Journal ArticleDOI
Determination of aflatoxin levels in nuts and their products consumed in South Korea
TL;DR: In this paper, a total of 85 nuts and their products marketed in South Korea were assessed for aflatoxins using a monitoring scheme consisting of enzyme-linked immunosorbent assay (ELISA) for rapid screening, high performance liquid chromatography (HPLC) for quantification and LC-mass spectrometry (MS) for confirmation.
Journal ArticleDOI
Fluorescence polarization immunoassay based on a monoclonal antibody for the detection of ochratoxin A
Won-Bo Shim,Anna Yu Kolosova,Anna Yu Kolosova,Yoon Jung Kim,Zhengyou Yang,Seon-Ja Park,Sergei A. Eremin,In-Seon Lee,Duck-Hwa Chung +8 more
TL;DR: A fluorescence polarization immunoassay (FPIA) based on a monoclonal antibody for the determination of ochratoxin A (OTA) was developed in this article.
Journal ArticleDOI
One-step simultaneous immunochromatographic strip test for multianalysis of ochratoxin a and zearalenone.
TL;DR: The developed OS-ICG offers a rapid, easy-to-use, and portable analytical system and can be used as a convenient qualitative tool for the on-site simultaneous determination of OTA and ZEA in cereals, food, and agricultural products in one analytical cycle.
