Assembled To Prepare Functional Particles Based Microfluidic Chip And Dry Since

Functional particles with special features such as electric, magnetic, or optical characteristics applied in various fields have aroused widely attention. Fabrication methods for functional microspheres are many, recently microfluidic and self-assembly are two methods being extensively studied.Over conventional processes, microfluidic processes allow the production of the monodisperse, size and shape-controlled microspheres with special features, which has been applied in various fields including photonics materials, self-assembly behavior, biological analysis, and drug delivery systems during the past two decades.Self-assembly of colloidal particles into crystalline arrays present an interesting approach to fabricate novel materials with advanced functionality. These artificial structures have properties such as long-range ordering, maximal packing density, well-defined pore size, and high surface-to-volume ratio make these assemblies usable in areas such as photonics, antireflective coatings, sensing, separation processes, catalysis, and anisotropic particle fabrication.This topic research mainly around two methods of microfluidic and self-assembly to fabricate functional particles. Microfluidic can produce polymer microspheres with function such as magnetic; while self-assembly method is mainly used dry self-assembly to prepare supraparticle with structural color.
