Droplet actuation on a digital microfluidic chip using a 5 volt battery

Rezaei Nejad H., University of British Columbia, CA

This paper presents a circuit using a 5-volt DC battery to actuate droplets on a DMF chip. The output of the circuit is a controllable high voltage, high frequency AC signal which can actuate a [...]

DNA repair enzyme analysis on EWOD fluidic microprocessor

Jary D., Chollat-Namy A., Fouillet Y., Boutet J., Chabrol C., Castellan G., Gasparutto D., Peponnet C., CEA, FR

DNA repair enzyme analysis on EWOD fluidic microprocessor An original analytical assay, aimed at monitoring DNA lesions repair activities has been combined to a dedicated microfluidic EWOD (electrowetting on dielectric) microprocessor.The quantification of enzymatic repair activities [...]

An Analytical Model for the Prediction of Microdrop Extraction and Splitting in Digital Microfluidics Systems

Berthier J., Raccurt O., Clementz Ph., Jary D., Claustre P., Peponnet C., Fouillet Y., CEA-LETI, FR

In the preceding text submitted to Nanotech 2005, we have demonstrated that surface tension is the dominant force on liquid microdrops in EWOD microsystems and that the problem is mostly topological. Minimization of the surface [...]

A Computational Model for the Design of ElectroWetting On Dielectric (EWOD) Systems

Bedekar A.S., Jenkins J.W., Sundaram S., CFD Research Corporation, US

Microfluidics has enabled the development of integrated lab-on-a-chip (LoC) devices for use in a clinical diagnostics, high throughput screening, drug discovery, biodefense and environmental monitoring. Although most microfluidic devices are based on continuous flow of [...]
