In this paper, an electrochemical sensing platform based on gold nanoparticle modified carbon nanofiber (CNF@AuNPs) as working electrode is proposed for the high sensitivity and selective determination of metronidazole. Meanwhile, the sensor has a large linear response range from 0.1 to 2000 μM, the limit of detection for metronidazole (MNZ) is as low as 0.024 μM. The sensor is simple to prepare and reproducible, and it shows good results in MNZ analysis of tap water.
