N2 - Recently, we demonstrated the fabrication of three-dimensional shaped particles from a microfluidics-based approach called optofluidic fabrication [1]. Now, by incorporating a time dimension within the particle fabrication process, we have created particles with geometries that cannot be created using conventional flow lithography techniques. This 4D optofluidic fabrication relies on three coupled processes: (1) inertial flow shaping, (2) density-assisted flow shaping, where a density mismatch between fluids further alters flow cross-sections, and (3) UV light polymerization. By varying flow conditions, density difference, and UV light patterns, an infinite set of highly anisotropic particles can be produced.
