41. 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 ...

42. Selective DNA Sensing Elements Integrated Into Microfluidic Channels
Topic: Microfluidics
Published: 12/1/2003
Authors: Rebecca A Zangmeister, Michael J Tarlov
Abstract: This paper describes the development of a unique fluorescence based DNA diagnostic assay that does not require pre-labeling of the target oligomer prior to analysis. The assay uses polyacrylamide hydrogel plugs immobilized in microfluidic channels, ...

43. 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 ...

44. Solution and Surface Composition Gradients via Microfluidic Confinement: Fabrication of a Statistical-Copolymer-Brush Composition Gradient
Topic: Microfluidics
Published: 6/6/2006
Authors: Chang Xu, Susan E. Barnes, Tao Wu, Daniel A Fischer, Dean M DeLongchamp, J Batteas, Kathryn L Beers
Abstract: A simple method to generate solution gradients through microfluidic confinement is described. The solution gradient inside a microchannel was formed by varying the relative infusion rates of two solutions that differed in compositions. The establishm ...

45. Temperature Measurement and Control in Microfluidic Systems
Topic: Microfluidics
Published: 10/1/2001
Authors: David J Ross, Michael Gaitan, Laurie E Locascio
Abstract: We describe a technique for the measurement of fluid temperatures in microfluidic systems based on temperature-dependent fluorescence. The technique is easy to implement with a standard fluorescence microscope and CCD camera. The efficiency of the me ...

48. Three dimensional aspects of droplet coalescence during dropwise condensation on superhydrophobic surfaces
Topic: Microfluidics
Published: 8/24/2011
Authors: Konrad Rykaczewski, John Henry Scott, Sukumar Rajauria, W Robert Ashurst, Jeff Chinn, Amy Chinn, Wanda Jones
Abstract: We report formation of nano-to-microscale satellite droplets in the geometrical shadow of high contact angle primary drops during dropwise water condensation on a nanostructured superhydrophobic surface. The primary drops contribute to the heat tran ...

49. Unexpectedly high encapsulation efficiency in nanometer scale liposomes with hydrodynamic focusing using continuous-flow microfluidcs
Topic: Microfluidics
Published: 10/20/2008
Author: Andreas Jahn
Abstract: A method is presented for achieving high entrapment efficiencies of a hydrophilic drug simulant, sulforhodamine B (SRB), in nanometer-scale liposomes using a continuous-flow microfluidic system. Liposome size and size dispersion are determined using ...
