Summary:This paper presents a versatile microfluidic platform for producing anisotropic polymeric microparticles of controlled sizes and size distributions. Using a planar sheath-flow geometry fabricated on a glass chip, we generated monodisperse organic droplets consisting of two differently colored miscible segments; these droplets were subsequently polymerized to form monodisperse Janus microspheres having both electrical and color anisotropy. Those particles could be used for an electronic paper application. We also engineered particles of geometrical anisotropy by using two immiscible organic fluids as the raw material. Multiple-channel integration for scale-up of productivity was also demonstrated.
