Abstract

We show that it is possible to direct particles in a fluid much like rays of light in optics. We demonstrate refractive, focusing and dispersive elements for particles flowing through suitably constructed metamaterials: obstacle arrays with built-in asymmetry. We also configure these elements to address the problem of diffusion limited mixing in microfluidics. We show it is possible to cross dye or particle jets with a second particle stream and apply this concept to on-chip, continuous flow, “label & wash” of blood platelets. The unusual aspects of these hydronic metamaterials could be of great use for on-chip bio-particle mixing, separation and analysis.
