Key Points

The main aim is to develop a method for rapid and selective detection of oxytetracycline residues.
Synthesis of pyrene-based fluorescent molecularly imprinted polymer
Assessment of detection performance based on inner filter effect
Evaluation of selectivity and sensitivity in various samples
The polymer showed effective and selective binding to oxytetracycline.
Rapid detection was achieved with minimal interference from other substances.
Significantly enhanced fluorescence signal was observed in the presence of OTC.

Implication

This work demonstrates rapid and selective detection of oxytetracycline residues, indicating its potential usefulness in safety monitoring.

Abstract

Oxytetracycline (OTC) residues have seriously threatened human health, as they may trigger allergic responses, hepatotoxicity, and the development of bacterial resistance. Detecting OTC in samples is therefore important. This work...
