ABSTRACT: Core@shell nanoparticles are advanced functional materials with modified properties combined into a single unity leading to their enhanced physico-chemical properties. In biomedical field, bi/tri/or multi-metallic Gold-Based Nanocrystals (GBNCs) and metamaterials, with core@shell heteronanostructures exhibit superior plasmonic properties with a broad range from sensing technology to nanomedicine. In this review paper, we investigated the recent trends of gold nanoparticles with a particular focus on core@shell heteronanostructured materials and their application in biomedical engineering. All properties are due to their size, shape, and structure-dependent Localized Surface Plasmon Resonances (LSPRs); owing to the enhancement of the plasmonic properties of isotropic and anisotropic Au NPs, including Quantum dots that are tailored to generate electromagnetic “hots sports”; highly sensitive for the diagnostic and therapeutic applications.
