At the Rowland, the Hur Lab focused on developing innovative microfluidic techniques for sheathless particle positioning, cellular biophysical property measurements and label-free target cell purification. Inertial Focusing is a unique microscale hydrodynamic phenomenon, which can be utilized to accomplish aforementioned purposes. By fine-tuning microchannel geometries and flow conditions, the lateral location of flowing particles with a wide range of varying sizes, mechanical stiffnesses and shapes, could be precisely controlled. They envisioned that Inertial Microfluidics would enable development of simple and cost effective target cell identifcation/purification techniques, which would have beneficial impact for numerous clinical and research applications.
