Designing colloidal suspensions for directed materials assembly

Recent advances in microfluidic and direct-write assembly of colloidal suspensions open new avenues for microscale patterning of functional materials with controlled composition, geometry, and properties. In this article, we describe fundamental aspects of suspension structure, elasticity, and flow behavior for three important systems: (1) dense liquids (and glasses), (2) gels, and (3) biphasic mixtures. We also highlight examples from the current literature of colloidal architectures patterned by these emerging methods.
