41. 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 ...

44. 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 ...

45. 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 ...

46. 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, ...

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

48. DNA Hydrogel Plugs Immobilized in Microfluidic Channels with Improved Stability
Topic: Microfluidics
Published: 2/28/2002
Authors: Rebecca A Zangmeister, K G Olsen, David J Ross, Michael J Tarlov
Abstract: It has been previously demonstrated that DNA, modified on the 5' end with an acrylic acid group, can be incorporated into a polyacrylamide hydrogel matrix. These types of DNA containing gels have recently been immobilized in plastic microfluidic cha ...

49. 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 ...

50. Temperature Measurement in Microfluidic Systems Using a Temperature-Dependent Fluorescent Dye
Topic: Microfluidics
Published: 9/1/2001
Authors: David J Ross, Michael Gaitan, Laurie E Locascio
Abstract: A technique is described 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. In addition, the meth ...
