Functional microparticles are widely used in various fields

such as delivery and controlled release of drugs

encapsulation and protection of active materials

micro-reactions and micro-separations. Compared with traditional techniques for preparing microparticles

microfluidic technique provides an advanced platform for fabrication of monodisperse functional microparticles with well-controlled structures and functions. This review summarizes recent progress of microfluidic fabrication of novel functional microparticles. Emphases are focused on controllable fabrication of monodisperse spherical

non-spherical

hollow

core-shell

hole-shell

and multi-compartment microparticles by microfluidic techniques.
