“…With the increase of CAP-contaminated food and the environment, detection methods give rise to attention. The traditional detection methods of CAP include microbiological assay, 7 immunoassay, [8][9][10] and standard techniques, such as High-Performance Liquid Chromatography (HPLC), 9,11,12 LC-MS, 13,14 and GC-MS. 15 The first two methods cannot achieve quantitative detection and are prone to false positives. 7 The traditional detection methods are reliable for the analysis of CAP but still are restricted for most instruments expensive and demand laboratory setup, professional operation, and high operating costs.…”

Chloramphenicol (CAP), a broad-spectrum antibiotic, has severely impacted human health and the ecological environment, which brings an increasing demand for an efficient monitoring technology for rapid and sensitive antibiotic residue detection. Herein, a highly sensitive and selective electrochemical sensor was developed for detecting CAP, based on the synergistic effect of β-cyclodextrin (β-CD) and CuO-nanomaterials modifying glassy carbon electrode (GCE). Scanning electron microscopy and X-ray diffraction analysis were used for morphological characterization. β-CD/CuO/GCE sensor with high-specific surface area and cavity structure was prepared by modifying GCE for further electrochemical testing. Experimental parameters were optimized using square wave stripping voltammetry. The developed sensor obtains an ultra-wide linear range from 1.0 × 10−7 to 5.0 × 10−4 mol l−1and the limit of detection is 0.5 × 10−7 mol l−1. The sensor displays high sensitivity, remarkable stability, and reproducibility; particularly more convenient than the liquid chromatography-mass spectrometry (LC-MS) verification method. Furthermore, the applicability of the developed β-CD/CuO/GCE sensor was demonstrated by detecting CAP in food samples.
