In this paper several electrodes architectures are modeled, implemented and compared in order to optimize the integration of hybrid micro-system for lab-on-a-chips (LoC). This study highlights the limitations of finite element simulations for a hybrid and complex micro-systems and propose new approach to overpass some fabrication constraints in a LoC design. The proposed LoC is based on dielectrophoresis...
In recent years, there has been increasing interest in monitoring and controlling of pH. It has become an important aspect of many industrial wastewater treatment processes. At the same time, the demand for smaller electronic devices used for various industrial and commercial applications has greatly increased. Micro and nano materials, such as Carbon Nanotubes (CNTs), are known for their excellent...

We report on a novel optoelectronic tweezers (OET) that integrates with multilayer PDMS based microfluidic devices for the first time. This is realized by coating the PDMS channels with a Au mesh electrode capable of providing an electrically conductive and optically transparent surface that bonds with an OET surface as well. Microfluidic integrated OET not only allows continuous delivery of biological...
We demonstrate a general method to assemble and contact arrays of individual multiwall carbon nanotube (MWCNT) interconnects between electrodes in one batch. We have also collected about 200 resistance measurements to compare four different contact metals: Al, Au, Ti, and Pd. We have also measured the radio frequency characteristics of the assembled MWCNTs up to 15 GHz. High-resolution transmission...
The dielectrophoretic attraction of matter into the regions of highest field strength when a non-uniform electric is present has been utilized in the separation of solid materials of differing dielectric constants and again in the extraction of solid particles from suspension in liquids.1–4 The present study was designed to explore the effects upon dc conduction through dielectric liquids when solid...
