Research Progress in Rapid Detection of Tetracycline Using Fluorescent Nanoprobes

Tetracycline (TC) is an important broad-spectrum antibiotic. As a commonly used veterinary drug, TC can accelerate the growth of livestock and poultry and prevent the occurrence of diseases. However, when unreasonably applied, TC may remain in animal-derived food, posing many potential hazards. Rapid and accurate detection of TC and its residues is an important tool to ensure the safety and effectiveness of food matrices. In recent years, fluorescence nanoprobes have been used for the monitoring and visual analysis of complex food matrices, which have sparked widespread attention due to their high sensitivity, strong selectivity and high detection efficiency. This paper classifies the common fluorescent nanoprobes, summarizes and reviews rapid fluorescent methods that have been recently developed for the detection of TC, and discusses future directions in this field. It is expected that this paper will provide a reference for the establishment of methods for the accurate determination of TC content in complex food matrices.
