摘要

Main observation and conclusion Accurate determination of acetaminophen concentration is essential for studying the metabolic status of acetaminophen in clinical practice.In this study,nickel phosphide was used for electrochemical detection of acetaminophen for the first time.An electrochem-ical acetaminophen sensor based on Ni2P nanosheets was successfully constructed and the sensor showed many convincing proper-ties:(a) a good linear range (0.5 μmol/L-4.5 mmol/L);(b) a moderate sensitivity (131.1 μA·mmol-1·L·cm-2);(c) a low detection limit(0.107 μmol/L).In addition,the sensor also showed excellent selectivity,robust stability and reliable repeatability.Further experi-ments demonstrate that the prepared sensor can be used for quantitative detection of acetaminophen in commercial medical drugs.
