41. 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 ...

42. Generating Cell Arrays in Microfluidic Networks
Topic: Microfluidics
Published: 10/1/2005
Authors: Samuel P Forry, D. R. Reyes, Brian J. Polk, Michael Gaitan, Laurie E Locascio

43. Microfluidic Platform for the Generation of Organic-Phase Microreactors
Topic: Microfluidics
Published: 4/1/2005
Authors: Zuzanna T. Cygan, J Cabral, Kathryn L Beers, Eric J. Amis
Abstract: Rapid prototyping photolithography of a thiolene based resin was used to fabricate microfluidic devices stable to aliphatic and aromatic organic solvents. The swelling of the thiolene resin in various organic solvents was quantified and the solvent ...

44. Development of a Microfluidic Rheometer for Complex Fluids
Topic: Microfluidics
Published: 1/1/2005
Authors: Jai A Pathak, Robert F Berg, Kathryn L Beers
Abstract: Our group has recently published a report of a combinatorial rheometer/viscometer developed in our lab, based on the princinple of a damped harmonic oscillator. In this paper, we describe a modification of this approach to scale down this viscometer ...

45. Probing Electric Fields Inside Microfluidic Channels during Electroosmotic Flow with Fast-Scan Cyclic Voltammetry
Topic: Microfluidics
Published: 9/1/2004
Authors: Samuel P Forry, J R Murray, Michael L. A. V. Heien, Laurie E Locascio, R M Wightman

46. Microfluidic Mixing
Topic: Microfluidics
Published: 6/1/2004
Author: Laurie E Locascio

47. A New Synthetic Method for Controlled Polymerization of HPMA Using a Microfluidic System
Topic: Microfluidics
Published: 2/1/2004
Authors: Tao Wu, Ying Mei, J Cabral, Chang Xu, Kathryn L Beers
Abstract: Atom transfer radical polymerizations (ATRP) were performed in a microfluidic channel, fabricated in a solvent resistant polymer matrix. Compared to conventional batch polymerization, microfluidic platforms offer a unique opportunity to handle small ...

48. Elastic Flow Instability, Curved Streamlines and Mixing in Microfluidic Flows
Topic: Microfluidics
Published: 2/1/2004
Authors: Jai Avinash Pathak, David J Ross, Kalman D Migler
Abstract: Flow instabilities are well known to occur in macroscopic flows when elastic fluids flow along curved streamlines. In this work we use flow visualization to study the mechanism underlying a purely elastic flow instability for Poiseuille flow in a mic ...

49. 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, ...

50. Droplet-String Deformation and Stability During Microconfined Shear Flow
Topic: Microfluidics
Published: 1/1/2003
Authors: Jai Avinash Pathak, Kalman D Migler
