Graduate student Cicely Shillingford and undergraduate student Brandon present capillary assembly of liquid particles (CALP) as a microfabrication strategy to create arbitrarily shaped polymer colloids. In this method, emulsion particles are deposited into patterned microarrays within a fluidic cell, where coalescence, polymerization, and extraction then follows. Eleven geometrically diverse patchy and Janus particles are presented, including triblock ellipsoids, planar tetramer, and pentagonal patchy particles. The work contributes a method for the design and fabrication of micro/nanoparticles with more complex, multicomponent structure for the targeting of hierarchical functional materials, including use in filtration devices, sensors, diagnostics, solid-state catalysts, and optical electronics.
