The detection of chloramphenicol (CAP) is of paramount importance in safeguarding food safety and protecting human health. Herein, a photochemical (PEC) electrode combined with CAP molecular imprinted (TiO 2 -MIPC) films has been reported and then the PEC property has been utilized to realize light-elution function. The PEC theory has been used to accelerate the preparation of MIPs combined with special recognition of MIPs to enhance PEC sensors and their detection capacity. The SEM image shows that MIP films were deposited on a pipe orifice of the TiO 2 . The TiO 2 -MIPC sensor electrode exhibits high selectivity and sensitivity for determination of CAP, and the differential pulse voltammetry (DPV) analysis is highly linear over CAP concentrations of 0.1−20 ng/mL with a detection limit of 0.03 ng/mL (S/N = 3). Moreover, DFT calculations indicate that the combination mode of PANI@CAP may be hydrogen-bond interactions between amino and nitro groups, and the P/N junction of PEC-MIPC generates photogenic charge to break the hydrogen bond as well promote the self-elution function. Thus, this convenient and sensitive PEC sensor will improve the efficiency of hazardous substance detection and offer a design for future PEC sensors.

“…Due to its low cost, high efficiency, and excellent therapeutic effect, CAP is widely used in animal feed production, poultry, and aquaculture, as a drug or addition for treating and preventing bacteria. 1 Owing to the extensive and increasing use of CAP, which would easily remain in livestock, poultry, marine organisms, 2 and dairy products. Also, environmental resources have been contaminated with the chemical and its metabolites.…”

“…3 Antibiotic residues can be present in the food chain and further accumulate in food or the human body, through their use by foodproducing animals and some animal milk-secreting products. 1,4 Meanwhile, the high stability of CAP leads to its persistent existence or even expansion of harm in the body or environment, which will bring greater risk challenges. Long-term accumulation will pose a huge threat to human health, such as hepatic and renal toxicity, embryotoxicity, aplastic anemia, cardiovascular collapse, and even cancer.…”

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.
