Particles combining multiple anisotropy dimensions offer possibilitiesfor self-assembly that have not been extensively explored to date. Thescope for assembly of microparticles in which the anisotropy dimensionsof internal bond angle and chemical ordering have been varied isinvestigated. Colloidal assemblies with interesting open (i.e.,non-close-packed) structures can be assembled from these buildingblocks. The structure of the assemblies formed is linked to the buildingblock anisotropy because the steric constraints introduced inducedeviations from close packing. Key challenges addressed in pursuit ofthese structures are parallelization of microfluidic synthesis methods,simulation to efficiently search the available anisotropy space, andmethods that characterize the properties of the resulting assemblies.This combined program of synthesis, simulation, assembly, andcharacterization may be applied to develop design rules that guideefforts to fabricate microparticle building blocks and their assemblies.
