N2 - We present a unique fabrication scheme for the generation of non-spherical particles from inertial flow shaping and UV-polymerization. By utilizing fluid inertia within spiral microchannels and UV-reactive precursor fluids, complex shaped particles are created from two sequential processes: (1) Dean flow cross-sectional shaping, where the cross sectional area of UV-reactive and inert fluid streams are deterministically deformed by Dean vortices in a spiral channel, and (2) UV-polymerization, where micron-scale three-dimensional shaped particles are formed at the intersection of patterned UV light and UV-reactive fluids. Numerical and experimental results demonstrate Dean flow fluid stream shaping along with successfully fabricated three-dimensional particles.
