| Abstract |
Contamination with the antibiotic tetracycline (TC) used in animal husbandry is a serious problem in the food safety and environmental pollution fields and may cause severe diseases in humans. An effective strategy for detecting tetracycline at trace levels is therefore needed. Here, a combination of two effective strategies for enhancing the analytical performance of tetracycline detection, namely, a sensitive fluorescence method after a preconcentration step, was developed. Ultratrace tetracycline contamination was extracted with a hybrid functional nanocomposite of magnetic nanoparticles coated with a mixed metal hydroxide (MNPs@MMH), which were separated using a permanent magnet and transferred to a small volume of the eluting solution. Through the inner filter effect (IFE), the concentration of eluted tetracycline was effectively correlated with the decrease in emission intensity of the fluorescent probes (N,S-doped carbon nanodots; N,S-CDs). Under the optimal conditions, the detection range for tetracycline was 0.80 to 10 µM. The detection limit for TC sensing was 0.16 µM. This reported method was used to successfully detect tetracycline contamination in milk and water samples from an animal husbandry farm. |
