Abstract

We present the creation of complex 3D shaped particles using inertial flow deformation and UV polymerization. Our approach is comprised of two coupled processes: (1) Inertial flow in microchannels which precisely engineers the flow cross sectional shape of UV-reactive and inert fluid streams, and (2) Light activated polymerization where patterned UV light triggers the fluid polymerization process. Thus, various 3D shaped particles are created at the intersection of a horizontal extrusion of fluid and a vertical extrusion of patterned UV light. We present the results from a comprehensive numerical and experimental analysis of inertial flow deformation and particle fabrication.
