superhydrophobic surface(sHs) has been well developed, as sHs renders the property of minimizing the water/solid contact interface. Water droplets deposited onto sHs with contact angles exceeding 150°, allow them to retain spherical shapes, and the low adhesion of sHs facilitates easy droplet collection when tilting the substrate. These characteristics make sHs suitable for a wide range of applications. One particularly promising application is the fabrication of microsphere and supraparticle materials. sHs offers a distinct advantage as a universal platform capable of providing customized services for a variety of microspheres and supraparticles. In this review, an overview of the strategies for fabricating microspheres and supraparticles with the aid of sHs, including cross-linking process, polymer melting,and droplet template evaporation methods, is first presented. Then, the applications of microspheres and supraparticles formed onto sHs are discussed in detail, for example, fabricating photonic devices with controllable structures and tunable structural colors, acting as catalysts with emerging or synergetic properties, being integrated into the biomedical field to construct the devices with different medicinal purposes, being utilized for inducing protein crystallization and detecting trace amounts of analytes. Finally,the perspective on future developments involved with this research field is given, along with some obstacles and opportunities.
