© 2018 Elsevier Inc. After a long-term toxicity study on Bisphenol A (BPA), the European Union and U.S food and drug administration updating the rules regarding the usage of BPA by extending the prohibition of BPA to include in the production of papers, on February 2018. Therefore, it is essential to establish the trace level BPA detectors in paper samples. In this report, the synthesis of novel ZnO nanoclusters wrapped with reduced graphene oxide (ZnO NCs/rGO) and its application towards the selective electrocatalytic detection of BPA are described. Initially, ZnO NCs/rGO is synthesized by the one-step hydrothermal approach, and various characterizations explain the compound's compositions and structure. The significance of ZnO NCs/rGO together with good electrocatalytic properties leads this material to the platform for electrochemical sensor. Finally, ZnO NCs/rGO was fabricated and validated as an effective sensor for the sensitive detection of BPA. The demonstrated sensor revealed excellent detection of BPA with the very low detection limit (2.1 nM), and also it offered good analytical parameters with more extensive linear range and higher sensitivity. Likewise, the sensor annexes good durability, reproducibility, and selectivity towards the determination of BPA. Due to the nourishing capacity of the prepared ZnO NCs/rGO, it is employed for the detection of BPA in tissue paper samples.
