Printable Carbon Black/Graphite Conductive Ink toward Electrochemical Determination of Norfloxacin in Environmental Samples.

ABSTRACT: Norfloxacin (NOR), a fluoroquinolone antibiotic widely used to treat urinary tract infections and gastrointestinal disorders caused by bacteria, poses a significant environmental concern. The widespread use of NOR can lead to the development of antibiotic resistance in human populations and, upon release into the environment, can contaminate aquatic and terrestrial ecosystems, potentially impacting human and environmental health. This work aimed to develop an electrochemical sensor printed with a conductive ink composed of graphite (Gr), carbon black (CB), and stained-glass varnish (SGV) for the detection of NOR in environmental samples. The optimal ink composition demonstrated 33% Gr, 22% CB, and 45% SGV. The morphology of the proposed sensor was designed by scanning electron microscopy a
