Abstract

Polymeric particles are widely used in a variety of applications such as controlled delivery system, optical materials, chromatographic media, medical imaging, encapsulation of biolmolecules, and tissue engineering. The chemical and physical properties of polymeric particles including monodispersity, porosity, shape, size, surface charge, and hydrophilicity/ hydrophobicity significantly influence on particle function and performance. For example, the characteristic features such as nonspherical, anisotropical, and Janus particles are becoming increasingly important because of their role in performing the fundamental studies in self-assembly, microrheology, medical diagnosis, and photonic devices. Thus, the novel methodology for the generation of uniform particles with a large diversity of designing morphologies and chemophysical properties will be a promising platform technology in many advanced applications.

Microfluidics as an alternative route has recently emerged as one of promising tools to the synthesis of functional materials such as polymeric particles, microfiber, colloidosome, Janus particle, and anisotropical particles because it provides the precise control over particle shape, size, chemical compartmentation, and core/shell structure. Here, I will present our recent progress made in the synthesis of functional materials using microfluidic techniques such as droplet and laminar flow-based method. For example, we can produce a variety of polymeric particles from soft microgels to hard sphere under the combination of polymerization technique. In addition, microfluidic method continuously provides novel hollow microcapsule having core/ shell structure, Janus particles having organic and inorganic part, and microfibers from smooth to Janus topology. In addition, we will present the micromold technique containing confined two microfluids for the synthesis of anisotropical particles. We demonstrate a new way of particle synthesis with wide flexibility of distinct shapes, size, and compartmentation in 3 dimensional space.
