Three-dimensional particle focusing under viscoelastic flow based on dean-flow-coupled elasto-inertial effects

, 2016
Based on dean-flow-coupled elasto-inertial effects, 3D particle focusing in a straight channel with asymmetrical expansion–contraction cavity arrays (ECCA channel) is achieved. First, the mechanism of particle focusing in both Newtonian and non-Newtonian

Switchable 3D optofluidic Y-branch waveguides tuned by Dean flows [PDF]

Scientific Reports, 2016
AbstractOptical branch waveguides are one of the most important optical elements and have been widely exploited for optical communication systems. However, prevailing devices are typically solid and have limit in tunability. Liquid optical devices have attracted more interest for the advantage of tunability of liquid media, but their signals suffer ...
