摘要：

We have developed an electrorotation (ER) chip that has a sandwich structure in which interdigitated array (IDA) electrodes are arranged face-to-face. These IDA electrodes on the top and bottom of the chip were orthogonally arranged to form over 2000 square regions having rotating electric fields between the IDA electrodes. Since rotating electric fields can be generated by arranging the electrical connections to produce a pi/2 phase difference between adjacent electrodes, a large number of measurement areas for ER were incorporated within a single ER chip. The ER properties of glass microrods at the individual measurement areas were investigated using this ER chip. The present ER chip was found to be a useful tool for performing high-throughput assays to analyze the dielectric properties of microparticles. Crown Copyright (C) 2010 Published by Elsevier B.V.
