Current advances in immunoassays for the detection of antibiotics residues: a review

Abstract

ABSTRACT Food contamination with antibiotic residues has become a worldwide problem due to the heavy and improper use of antibiotics. The development of fast, high-throughput, easy, and economical screening methods for the detection of antibiotic residues is an important requirement as an alternative to the traditional assays. Immunoassays are widespread promising methods that can achieve the conditions of an analytical method in the evaluation of food and environmental protection. This review offers an overview of the preparation of antibodies and the currently established immune-assays for the antibiotic residues detection, including enzyme-linked immunosorbent assay, fluorescence immunoassay, radioimmunoassay, colloidal gold immunoassay, and chemiluminescence immunoassay. Furthermore, it will elaborate on the future perspective on the performance and improvement of these assays for the determination of antibiotic residues in food samples. These assays include a simple sample preparation and high-sensitive detection that offer a significant assurance for the screening of antibiotic residues.
