Tunnel Dielectrophoresis for Tunable, Single-Stream Cell Focusing in Physiological Buffers in High-Speed Microfluidic Flows.

A novel tunnel dielectrophoresis (TDEP) mechanism is demonstrated for continuously tunable, sheathless, 3D, and single-stream microparticle and cell focusing in high-speed flows in regular physiological buffers. Particles and cells showing negative DEP responses can be focused at the electric field minimum location regardless of their types and sizes.
