Abstract
The design and fabrication of a generic travelling wave dielectrophoretic separation system is presented. A range of technical issues have been addressed and resolved. These include the optimization of the electrical insulation and electrical contact between different electrode layers and the choice of materials. A new method for fabricating microfluidic liquid channels, the fluidic channel cover and the seal within the channel, as well as an effective sample introduction system has been developed. A complete particle handling and fractionation system has been fabricated and the functioning of the device demonstrated with latex particles.Keywords
