Abstract
This paper presents new results on manipulation of undiluted whole blood using traveling wave dielectrophoresis (twDEP). Although twDEP is not new, data on whole blood manipulation is rare. The twDEP in this work consists of four 2D electrodes of 20/spl mu/m width operating at 10MHz sinusoidal wave with 90 degree phase apart. Results show that whole blood bulk flow can be manipulated at-will in either direction. Moreover, simultaneous bi-direction motion is also observed at different height of the 25 /spl mu/m flow channel. This flow feature might be utilized for separation purpose.
