Electrochemical Characterization and Detection of the Antibiotic Compounds Over Modified Working Electrode

Abstract

The electrochemical characterization and detection of antibiotic compounds are essential to understand and address the issues of drug-resistance in bacteria. In this work, we have characterized a varieties of antibiotic compounds such as Ciprofloxacin, Tobramycin, and a novel hybrid of both Ciprofloxacin and Tobramycin (Cip-Tob) over modified and unmodified glassy carbon electrodes. The working electrodes were modified using various carbonaceous catalyst support such as Carbon Black and functionalized Carbon Nanotubes, etc. Various electrochemical measurements such as cyclic voltammetry and differential pulse voltammetry were performed and they revealed the ultra-sensitivity of the modified electrodes towards the detection of antibiotics.
