Description: 
4‑aminophenol (pAP) is a typical secondary product obtained in pharmaceuticals preparation that needs to be accurately measured to avoid dangerous collateral effects in drugs. According to European, United States and Chinese Pharmacopoeias authorities the level of pAP in drugs is limited to 50 ppm. Therefore, it is crucial to define suitable methods to fabricate innovative devices for a fast and accurate detection of these molecules. To this purpose, a strategy is presented combining fast detection methods such as Electrochemical Impedance Spectroscopy, Cyclic Voltammetry and Chronoamperometry taking advantage of the nanostructured electrodes' properties. In this work, we propose a simple and novel electrochemical sensor based on nanostructured electrode comprised of ZnO nanorods decorated by bimetallic (AuxPt1−x) Clusters. To finely tune the composition and the size of the metal nanoclusters we …
