✦ Synopsis


A technique is presented for the fabrication of large-area (20x20mm) multilayered electrode structures with 10p.m feature size. This technique has been used in the fabrication of 1000-electrode arrays powered by a series of interconnected bus-bars with quadrature-phased AC power supplies. These electrodes generate a travelling electric field which induces an asynchronous electrostatic linear force -Travelling Wave Dielectrophoresis -which can propel particles of micron to submicron scale and can be used for fractionation of subpopulations of such particles according to their dielectric properties.

## Abstract In this study, a useful method was developed to fabricate array patterns of microparticles not on electrode surfaces, but on arbitrary surfaces, using negative‐dielectrophoresis (n‐DEP). First, electrodes were designed and electric field simulations were performed to manipulate micropar
