Molybdenum disulfide-grafted carbon nanotubes for the electrochemical detection of acetaminophen with ultra-sensitivity.

ABSTRACT: The overuse of acetaminophen (APAP) poses significant health risks to human health, which necessitates the development of an efficient and rapid detection method for APAP. Hence, an electrochemical sensor using molybdenum disulfide-grafted carbon nanotubes (MoS₂/CNTs) was developed for the ultra-sensitive detection of acetaminophen (APAP). The linear detection range of the sensor was 0.07 to 150 µM, and the limit of detection for APAP was 0.43 µM. The MoS₂/CNTs composite demonstrated significantly enhanced catalytic activity toward APAP, attributed to its enormous specific surface area and effective electron transport characteristics. Electrochemical techniques, including impedance spectroscopy (EIS), cyclic voltammetry (CV), and differential pulse voltammetry (DPV),
