The shape‐controlled synthesis of nanocrystals remains a hot research topic in nanotechnology. Particularly, the fabrication of 1D structures such as wires, rods, belts, and tubes has been an interesting and important subject within nanoscience in the last few decades. 1D necklace‐like micro/nanostructures are a sophisticated geometry that has attracted increasing attention due to their anisotropic and periodic structure, intrinsic high surface area, abundant transport channels, exposure of each component to the surface, and multiscale roughness of the surface. These characteristics enable their unique electrical, optical, and catalytic properties. This review provides a comprehensive summary of the advanced research progress on the fabrication strategies, novel properties, and various applications of necklace‐like structures. It begins with the main fabrication methods of necklace‐like structures and subsequently details a variety of their properties and applications. It concludes with the authors’ perspectives on future research and development of the necklace‐like structures. Due to their intriguing and specific appearance and architecture, necklace‐like nanostructures carry some unique features over simple 1D nanogeometries. In this review, necklace‐like structures by focusing on their diverse synthetic strategies, distinctive properties, and applications, as well as future directions for fabricating and capitalizing on necklace‐like structures are summarized.
