Because of this special property, the fabrication and application of colloidal PhCs have attracted increasing interest from researchers. However, the angle dependence is disadvantageous for the construction of some optical materials and devices in which wide viewing angles are desired. Recently, a series of colloidal PhC materials with spherical macroscopic morphology have been created. Because of their spherical symmetry, the PBGs of spherical colloidal PhCs are independent of rotation under illumination of the surface at a fixed incident angle of the light, broadening the perspective of their applications. Because microfluidics was used for the generation of the droplet templates, the development of spherical colloidal PhCs has progressed significantly. These new strategies not only ensure monodispersity, but also increase the structural and functional diversity of the PhC beads (PCBs). These novel PCBs provide a bridge between PhCs materials and biomedical applications such as barcodes, label-free detection, cell culture and drug delivery, and this also leads PCBs to far-ranging real-world applications. In this review, we present the research progress on PCBs, including their design, preparation, and potential applications. Future developments of the PCB materials are also envisioned. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书附件1 -->
