In this study, we focus on the alteration of negative dielectrophoresis (n-DEP) caused by small amount of DNA labeling on the microbeads and propose a new design of microfluidic device for more sensitive DNA detection. In previous study, we proposed a new electrical technique for rapid detection of DNA amplified by polymerase chain reaction (PCR). The method is based on dramatic alteration of dielectrophoresis...
In this paper we propose the modeling and simulation using Comsol 3.5a of a microfluidic chip, capable to run several tasks such as focusing, mixing, sorting and trapping nano and microbeads. The microfluidic chip, based on Polydimethyl siloxane (PDMS) and Polyethylenenaphtalate (PEN), is cost effective, flexible and totally biocompatible. The fluidic part is controlled both by pressure driven flow...
