Multiplexed Localization in Bi-Layer Digital Microfluidic Systems

Abolhasani M., Devlin K.D., Najjaran H., Hoorfar M., Holzman J.F., The University of British Columbia Okanagan, CA

This paper reports a novel system-level design for digital microfluidic (DMF) devices. A DMF multiplexer structure based on a cross-referencing architecture is presented. The design makes use of bi-polar voltage activation and threshold effects to [...]

Biomolecular Adsorption Phenomena in Electrowetting-Based Digital Microfluidic Devices

Ahmadi A., Devlin K.D., Najjaran H., Holzman J.F., Hoorfar M., University of British Columbia, CA

Digital microfluidic lab-on-a-chip technology has been a new trend in miniaturizing biomedical platforms. However, nonspecific adsorption of these biomolecules has proven to be one the greatest sources of uncertainties for these biofluidic chips. Unwanted adsorption [...]

Determination of droplet shape in digital microfluidic systems using two-dimensional flow analysis

Ahmadi A., Najjaran H., Holzman J.F., Hoorfar M., University of British Columbia Okanagan, CA

A two-dimensional model for fluid flow in a digital microfluidic system is introduced, and the results are compared to experimental data. Resistive flow effects based upon contact line forces, filler effects and shear forces are [...]
