Abstract

Soft-lithography-based microfluidics and droplet break-off dynamics that can be combined to produce uniform colloidal assemblies from amonodisperse suspension was demonstrated. Experimental results showed that colloidal assemblies with a reasonable uniformity were prepared and the uniformity was enhanced as the number of the embedded particles was increased. For colloidal assemblies with a smaller number of particles, the present microfluidic device needed to be incorporated with a subsequent soft-microfluidic device to sort the assemblies by the number of the internal particles.
