abstract = "We engineer multi-layered co-axial flow of high viscosity (10 x viscosity of water) polymer fluid streams inside a microfluidic channel with inner diameter of 200μm. A miniaturized 3D printed microfluidic device, with three concentric nozzles, is used to produce a co-axial flow of four streams, where the cross-sectional diameter of the inner ring-shaped streams could be pinched below 100μm by an outer sheath flow hydrodynamically focusing the inner streams. The structured flow of viscous polymers is initiated and stopped in a cyclic manner by synchronously controlling the pumps and valves using a LabView script. We have demonstrated on-demand stopping of polymer (potentially photo-curable) streams, which is essential to the 'flow lithography (SFL)' process.",
