A Review on Carbon‐based Electrodes for Electrochemical Sensor of Quinolone Antibiotics

Quinolone antibiotic is known for its effectiveness in treating infectious disease, and has been used widely for humans and also in animals. Continuous use of antibiotics could promote antibiotic resistance as well as result in the accumulation of antibiotic residues in food. Therefore, monitoring the quinolone antibiotic is important. Meanwhile, carbon‐based electrode is known as a material that has been used widely for electrochemical sensor application. It has been used in its bare form and modified form to improve the electrode catalytic performance. In this review, we summarize the utilization of unmodified and modified carbon‐based electrode in detecting various types of quinolone antibiotics. It is expected to provide comprehensive information on related topics. The modified and unmodified carbon‐based electrodes for various types of quinolone antibiotics electrochemical detection applications have been summarized. The bare carbon‐based electrode has several advantages such as being more simple and relatively stable compared to the modified electrodes, whose electrode stability usually becomes a drawback for long‐term application. Nevertheless, modified carbon‐based electrodes could also enhance the catalytic activity and its selectivity.
