Nonspherical particles include various morphologies, such as snow-shaped, mushroom-shaped, dumbbell-shaped, H2O molecules-shaped, bowl-like. Their unique structures not only provide novel assembly units, but also bring many special physical and chemical properties. During the last ten years, micro/nanometer bowl-like particles and arrays have been given widely attention. Due to their large specific surface area, low structure symmetry, the bowl-like particles and bowl-like arrays have unique optical, magnetic properties and provide broad potential applications in nano-reactors, drug delivery, high-sensitivity sensor, data storage, assembly units, solar cell and other fields. This review gives a systematic overview on the recent advances in the fabrication and properties of the bowl-like particles and bowl-like arrays. First, various synthesis routes are introduced in detail, including the monolayer colloidal crystal template approach, the bowl-like array template approach, induced growth, heterodimeric particle approach, hollow microspheres invagination, seed polymerization, solvent-treatment approach. Next, the relationship between the structure and the property of the bowl-like particles and arrays are investigated according to the types of material. The diverse applications of the obtained materials are also summarized, for example photo catalysis, solar cells, micro/nanometer devices, sensors, and so on. Finally, the advantages and disadvantages of various synthesized methods are discussed and an outlook on future developments in this area is also provided.
