基于微流控技术制备微/纳米粒子材料

Micro-and nanoparticles with unique properties have broad applications in drug delivery, absorption separation, optical/electrical materials, and magnetic device, etc. Due to the huge volume-to-surface ratio and continuous flow characteristic, remarkable advantages have been made in organic chemistry, polymer synthesis and material preparation by employing microfluidic technology compared with the traditional batch reactor. This review summarizes the recent progress in microfluidic synthesis of micro-and nanoparticles. Microreactor system can precisely monitor and control the particle formation process. By using single emulsion as the template, spherical and non-spherical polymer/inorganic/noble metal/semiconductor particles are fabricated. Multi-emulsions are used as templates for fabricating core shell particles, Janus particles and microcapsules.
