Progress in Optical and Electrochemical Sensors for Detection of Quinolone Antibiotics in Food

Abstract

Quinolone antibiotic residues present a high risk for food safety and have gained widespread attention. Nanomaterials based sensors have the advantages of on-site application, sensitivity, and small sample volume requirement and has attracted significant interest in on-site detection technology research for quinolone antibiotics. This paper introduces the application of optical sensors including fluorescence, colorimetry, SERS, ICA and electrochemical sensors based on diverse nanomaterials in quinolone antibiotics detection and summarizes the characteristics of diverse sensors. The application of nanomaterials including quantum dots and upconversion in optical sensors, as well as those of carbon and metal nanomaterials and redox media in electrochemical sensors are reviewed and evaluated. The objective of this work is to provide new concepts for antibiotics detection in food and the development of sensors.
