Iron oxide nanostructures (IONs) in combination with graphene or its derivatives-e.g., graphene oxide and reduced graphene oxide-hold great promise toward engineering of efficient nanocomposites for enhancing the performance of advanced devices in many applicative fields. Due to the peculiar electrical and electrocatalytic properties displayed by composite structures in nanoscale dimensions, increasing efforts have been directed in recent years toward tailoring the properties of IONs-graphene based nanocomposites for developing more efficient electrochemical sensors. In the present feature paper, we first reviewed the various routes for synthesizing IONs-graphene nanostructures, highlighting advantages, disadvantages and the key synthesis parameters for each method. Then, a comprehensive discussion is presented in the case of application of IONs-graphene based composites in electrochemical sensors for the determination of various kinds of (bio)chemical substances.
氧化铁纳米结构（IONs）与石墨烯或其衍生物（如氧化石墨烯和还原氧化石墨烯）相结合，在设计高效纳米复合材料以提高许多应用领域中先进设备的性能方面具有巨大潜力。由于纳米尺度复合结构所展现出的独特电学和电催化性质，近年来人们越来越致力于调整基于IONs-石墨烯的纳米复合材料的性质，以开发更高效的电化学传感器。在本专题论文中，我们首先回顾了合成IONs-石墨烯纳米结构的各种途径，强调了每种方法的优缺点及关键合成参数。然后，针对基于IONs-石墨烯的复合材料在电化学传感器中用于测定各种（生物）化学物质的应用情况进行了全面讨论。
