ReviewAnisotropic Microparticles from Microfluidics
The Bigger Picture
Anisotropic microparticles, which assume different properties depending on their direction, have become a research hotspot because subtle changes in particle anisotropy can create surprising effects. Benefiting from their anisotropic nature, these microparticles are capable of breaking through the limitation of general isotropic particles and combining diverse functions within a single particle entity, thereby adding significant value in an extremely wide range of areas including display, sensing, drug delivery, and cell culture. The emerging microfluidic technique offers a powerful platform for the controllable synthesis of anisotropic microparticles with excellent mono-dispersity and intricate morphology, facilitating the development of anisotropic microparticles in various areas. In this review, the basic principle of the microfluidic technique is briefly introduced, followed by the emphasis on the fabrication and application of anisotropic microparticles from microfluidics. In addition, perspectives on the future development and challenges associated with the fabrication of anisotropic microparticles through microfluidics are presented in terms of different applications.
