Abstract

Diverse patterns of flows in microfluidic channels have been utilized with great interests in the field of mixing, separation, and flow cytometry for high throughput analysis of chemical reagent or biomolecules. In this paper, we describe a new approach, hydrodynamic focusing lithography (HFL), in which the structuring of fluids in microflows combined with lithography is exploited to create large arrays of functional microparticles. Contrary to our prior flow lithography method, here the flows are stacked in multiple dimensions. We also demonstrate the utility of this process in a number of assays ranging from patterning of proteins to reinforced gel particles.
