Focusing, spacing control and resistance based sorting of deformable objects

This paper reports a novel hydrodynamic technique for the size based sorting of deformable objects. Device comprises two modules: focusing and spacing control module and sorting module. 3D analytical model was developed for the device analysis. Experiments were performed for the size based sorting of droplets (sizes 25 and 40 μm) and sorting efficiency of 70-94% was obtained depending on the size contrast.
