Core–shell nanostructures as a platform for sensing applications

Abstract In this chapter, we thoroughly explore core–shell nanostructures as a platform for various sensing applications. We cover both fundamental science and the current progress achieved in this field. The first part of the paper focuses on the types, properties, and applications of diverse core–shell-nanostructure-(CSN)-based materials (nanoparticles, quantum dots (QDs), carbon nanotubes (CNTs), graphene, nano porous materials, and nanocomposites/hybrid materials). Then, sensor design (electrochemical, colorimetric, fluorescent) and the fabrication of CSN materials are explained based on their working principles as they apply to photo electrochemical, electromechanical, electromagnetic, and other sensor applications.
