Abstract:

To understand the development and application of labeled immunoassays in the determination of pesticide and veterinary drug residues, the basic principles, advantages and disadvantages of five common labeled immunoassays including radioimmunoassay, enzyme immunoassay, luminescent immunoassay, fluorescence immunoassay and colloidal gold immunoassay were introduced and summarized in this paper, and their applications in determination of pesticides and veterinary drugs in recent years were described as well. Additionally, some existing problems and future trends of these immunoassays for pesticides and veterinary drugs analysis were discussed. The results showed that the described above immunoassays were proved to be simple, rapid, accurate, and of high specificity and sensitivity. It is believed that in the near future they will probably become one of the most promising methods for detecting residual pesticides and veterinary drugs and provide powerful technical support for the edible security of agricultural products.
