Publication date: Available online 9 April 2019Source: TrAC Trends in Analytical ChemistryAuthor(s): Pramod K. Kalambate, Dhanjai, Zeimei Huang, Yankai Li, Yue Shen, Meilan Xie, Yunhui Huang, Ashwini K. SrivastavaAbstractCore-shell nanomaterials (CSNs) have achieved huge popularity due to multifunctional properties achieved by manipulation of core or shell materials. This review highlights recent development in CSNs based sensing devices such as electrochemical sensors, optical sensors, wearable sensing devices, and gas adsorptive sensors, which find potential applications in numerous fields ranging from industrial, clinical, biological, environmental and food analysis. Furthermore, flexible and high deformation monitoring piezoresistive wearable sensors based on CSNs are found to be promising for monitoring of human physiological parameters and other body movements. Various synthetic strategies with a modern classification approach are explained with suitable examples. Several interesting properties of CSNs including high surface area, high conductivities, and high ion transport properties with biocompatibilities are best suited for developing ideal sensing devices. Future research directions with motivated research are highlighted in the conclusion part.Graphical abstract
