中文摘要：用胶体金、量子点及聚苯乙烯微球作为三种侧流免疫层析法(ICAs)的标签，来检测谷物样品中的玉米赤霉烯酮(ZEN)。结果表明，三种方法的LODs均低于大多数标准化机构设定的ZEN最大限值。
外文摘要：Colloidal gold, quantum dots and polystyrene microspheres were used as labels in three kinds of lateral flow immunochromatographic assays (ICAs) for the detection of zearalenone (ZEN) in cereal samples. The assays allow ZEN to be quantified within 20 min. The LODs are 10 μg·L−1 of ZEN for the colloidal gold-based ICA, and 1 μg·L−1 for both the quantum dot and polystyrene microsphere based ICAs. The respective data are 60 μg·kg−1, 6 μg·kg−1 and 6 μg·kg−1, respectively, for spiked samples and cereals. Only minor cross-sensitivity occurred between ZEN and fusarium toxins, and no cross-sensitivity if found for aflatoxin B1, T-2 mycotoxin, ochratoxin A, deoxynivalenol, and fumonisin B1. LODs of the three assays are lower than the maximum limits of ZEN set by most standardization agencies.
