11. Control of Flow Direction in Microfluidic Devices with Polyelectrolyte Multilayers
Published: 12/1/2000
Authors: S L. Barker, David J Ross, Michael J Tarlov, Michael Gaitan, Laurie E Locascio
Abstract: Electroosmotic flow (EOF) is commonly utilized in microfluidics. Because the direction of the EOF can be determined by the substrate surface charge, control of the surface chemical state offers the potential, in addition to voltage control, to direct ...

13. Controlled Encapsulation of a Hydrophilic Drug Simulant in Nano-Liposomes Using Continuous Flow Microfluidics
Published: 6/4/2008
Authors: Andreas Jahn, Joseph Earl Reiner, Wyatt N Vreeland, Don DeVoe, Laurie E Locascio, Michael Gaitan
Abstract: A new method to tailor the size and size distribution of nanometer scale liposomes and control loading of liposomes with a model drug in a continuous-flow microfluidic design is presented. Size and size dispersion are determined with tandem Asymmetr ...

14. Controlled Vesicle Self-Assembly in Continuous Two Phase Flow Microfluidic Channels
Published: 6/10/2004
Authors: Andreas Jahn, Wyatt N Vreeland, Laurie E Locascio, Michael Gaitan
Abstract: The spontaneous self-assembly of phospholipids into liposomes in aqueous solution results in the encapsulation of reagents into quantized packets in a manner that mimics cellular life-processes. Since their discovery in 1965, liposomes have been used ...

15. Controlled Vesicle Self-Assembly in Microfluidic Channels with Hydrodynamic Focusing
Published: 12/18/2003
Authors: Andreas Jahn, Wyatt N Vreeland, Michael Gaitan, Laurie E Locascio

16. DHS Leads the Way to Standards for Homeland Security
Published: Date unknown
Author: Laurie E Locascio
Abstract: In late April 2005, in response to a recently issued GAO report describing the urgent need for standards and validated methods related to biological incident response, Dr. Bert Coursey, head of the Standards Portfolio at DHS, charged NIST with the ta ...

17. DNA ENTROPOPHORESIS: A BALANCE OF ENTROPY AND DIFFUSION IN COMPLEX NANOCONFINEMENT
Published: 10/3/2011
Authors: Samuel M Stavis, Jon C Geist, Michael Gaitan, Laurie E Locascio, Elizabeth A Strychalski
Abstract: Entropophoresis ‹ motion caused by an entropy gradient ‹ is a novel nanofluidic method to direct the self-transport of biopolymers that established a new paradigm of nanofluidic functionality with broad relevance to lab-on-a-chip technol-ogy. He ...

18. DNA Molecules Descending a Nanofluidic Staircase by Entropophoresis
Published: 1/26/2012
Authors: Samuel M Stavis, Jon C Geist, Michael Gaitan, Laurie E Locascio, Elizabeth A Strychalski
Abstract: A complex entropy gradient for confined DNA molecules was engineered for the first time. Following the second law of thermodynamics, this enabled the directed self-transport and self-concentration of DNA molecules. This new nanofluidic method is term ...

19. Derivatization of Plastic Microfluidic Devices With Polyelectrolyte Multilayers
Published: 5/1/2000
Authors: S L. Barker, Michael J Tarlov, M L Branham, J Xu, William Ambrose MacCrehan, Michael Gaitan, Laurie E Locascio
Abstract: Microchannels fabricated in plastic materials by room temperature imprinting demonstrate large variability in surface charge as a result of the fabrication procedure. Surface charged groups are primarily localized on the channel walls and not on the ...

20. Detection of Viable Cryptosporidium Parvum Using DNA-Modified Liposomes in a Microfluidic Chip
Published: 7/1/2001
Authors: M. B. Esch, Laurie E Locascio, Michael J Tarlov, R. A. Durst
Abstract: This paper describes a microfluidic chip that enables the detection of viable Cryptosporidium parvum by detecting RNA amplified by nucleic-acid sequence-based amplification (NASBA). The mRNA serving as the template for NASBA is produced by viable C ...
