11. Reproducibility and Robustness of a Real-Time Microfluidic Cell Toxicity Assay
Topic: Microfluidics
Published: 5/15/2011
Authors: Gregory A Cooksey, John T Elliott, Anne L Plant
Abstract: Numerous opportunities exist to apply microfluidic technology to high-throughput and high-content cell-based assays. However, maximizing the value of these assays for drug discovery, screening or toxicity evaluation, for example, will require va ...

12. Microfluidics Measurements of Interfacial Rheology
Topic: Microfluidics
Published: 1/18/2011
Authors: Jeffrey D Martin, Joie N Marhefka, Kalman D Migler, Steven D Hudson
Abstract: The bulk properties and structural characteristics of emulsions arise substantially from their interfacial rheology, which depends strongly on surfactant mass transfer and its coupling to flow. Typical methods used to measure such properties often e ...

13. Quantitative Permittivity Measurements of Nanoliter Liquid Volumes in Microfluidic Channels to 40 GHz.
Topic: Microfluidics
Published: 12/1/2010
Authors: James C Booth, Nathan Daniel Orloff, Jordi Mateu, James A Beall, Matthew Rinehart
Abstract: We describe the design, fabrication, and evaluation of a new on-wafer measurement platform for the rapid, quantitative determination of the complex permittivity of nL fluid volumes over the frequency range from 10 MHz - 40 GHz. Our measurement platfo ...

17. Microwave-Induced Adjustable Nonlinear Temperature Gradients in Microfluidic Devices
Topic: Microfluidics
Published: 9/29/2010
Authors: Jayna J Shah, Jon C Geist, Michael Gaitan
Abstract: We present a technique to induce temperature gradients in flexible microfluidic devices with microwave energy. Microwave power decays exponentially in the propagating medium, and the rate of decay is higher for water compared to polymers or glass du ...

18. Separation and Metrology of Nanoparticles by Nanofluidic Size Exclusion
Topic: Microfluidics
Published: 8/11/2010
Authors: Samuel M Stavis, Jon C Geist, Michael Gaitan
Abstract: A nanofluidic approach to the separation and metrology of nanoparticles is demonstrated. Advantages of this approach include nanometer-scale resolution, nanometer-scale to submicrometer-scale range, mitigation of hydrodynamic and diffusional limitat ...

19. Using Microfluidic Channels to Determine ZThe Quantitative Permittivity of Nanoliter Fluid Volumes from 50 MHz TO 40 GHz USING MICROFLUIDIC CHANNELS TO DETERMINE THE QUANTITATIVE PERMITTIVITY OF NANOLITER FLUID VOLUMES FROM 50 MHZ TO 40 GHZ
Topic: Microfluidics
Published: 7/30/2010
Authors: James C Booth, Nathan Daniel Orloff, Xiaoli Lu, Yu Wang, Eduard Rocas, Jordi Mateu, Juan C. Collado Gomez, Michael D Janezic
Abstract: We describe the development of coplanar waveguide measurement structures integrated with microfluidic channels in order to rapidly determine the broadband dielectric properties of nanoliter volumes of fluids, fluid mixtures, and colloids over the ran ...
