61. Miniaturization of Bioassays for Toxicological Analysis
Laurie E Locascio
62. Molecularly-Imprinted Stationary Phases for Plastic Microchip-Based Capillary Electrochromatography
A. C. Henry, David J Ross, Laurie E Locascio
63. Nanomaterial Toxicity: Emerging Standards and Efforts to Support Standards Development
Laurie E Locascio, Vytautas Reipa, Justin M Zook, Richard C. Pleus
For the first time in the history of industrialization, nanotechnology offers the unique opportunity to consider material safety ahead of its full implementation. Many scientists around the world have been motivated by this and are working on develo ...
64. Nanoslinky: DNA Entropophoresis Down a Nanofluidic Staircase
Elizabeth A Strychalski, Laurie E Locascio, Samuel M Stavis, Michael Gaitan
Almost all nanofluidic devices for biopolymer analysis have been limited by one or two confining structural dimen-sions or the application of external forces for biopolymer manipulation, which has restricted the scope of related lab-on-a-chip technol ...
65. Nature s Packaging: Using Bio-Inspired Liposomes for Rapid, High Efficiency Mixing in Microfluidic Systems
Wyatt N Vreeland, Laurie E Locascio
66. On-chip CO2 control for microfluidic cell culture
Samuel P Forry, Laurie E Locascio
Carbon dioxide partial pressure (PCO2) was controlled on-chip by flowing pre-equilibrated aqueous solutions through control channels across the device. Elevated PCO2 (e.g. 0.05 atm) was modulated in neighboring stagnant channels via equilibration th ...
67. Optical Manipulation and Fusion of Liposomes as Microreactors
S Kulin, N Kishore, Kristian Helmerson, Laurie E Locascio
We present an all optical method to manipulate and fuse giant liposomes, typically 10 nm in diameter. Optical tweezers are used to trap two individual liposomes, which are then brought into contact. A single pulse of ultraviolet laser light focused ...
68. Optical manipulation of nano-containers for biotechnology
Kristian Helmerson, Joseph Earl Reiner, E Edgu-Fry, J M. Wells, Rani Kishore, Laurie E Locascio, M K. Gilson
69. Patterning Retinal Cells on Polyelectrolyte Multilayers
Darwin R Reyes-Hernandez, Elizabeth M. Perruccio, Patricia Becerra, Laurie E Locascio, Michael Gaitan
The patterning of retinal epithelial cells on polyelectrolyte multilayer (PEMs) lines is presented. PEMs were deposited in discrete lines using a poly(dimethylsiloxane) (PDMS) microfluidic network on top of a flat PDMS slab. The layers were formed by ...
70. Peak Compression and Resolution for Electrophoretic Separations in Diverging Microchannels
David J Ross, C F Ivory, Laurie E Locascio, K E Van Cott
We report the results of experiments and simulations on electrokinetic flow in diverging microchannels (with cross sectional area that increases with distance along the channel). Because of conservation of mass and charge, the velocity of an analyte ...
