Polyelectrolyte Multilayers

January 23, 2006
Author(s)
Darwin Reyes-Hernandez, Laurie E. Locascio, Michael Gaitan
The process of self-assembly occurs naturally in living systems to form complex structures out of random events in an incredibly accurate way. Order out of disorder is achieved in a fashion that is analogous to a jigsaw puzzle where each piece fits

Liposomes As Model Cellular Systems

December 21, 2004
Author(s)
Laurie E. Locascio, Wyatt N. Vreeland, Andreas Jahn, Michael Gaitan
The discovery that phospholipids spontaneously form fluid-filled bubbles when exposed to aqueous solution was first made by Alec Bangham in the early 1960's while studying the effects of phospholipids on blood clotting in the Babraham Institute in England

Micropatterning Neuronal Cells on Polyelectrolyte Multilayers

July 7, 2004
Author(s)
Darwin Reyes-Hernandez, Elizabeth M. Perruccio, Patricia Becerra, Laurie E. Locascio, Michael Gaitan
This paper describes an approach to adhere retinal cells on micropatterned polyelectrolyte multilayer (PEM) lines adsorbed on polydimethylsiloxane (PDMS) surfaces, using microfluidic networks. PEMs were patterned on flat oxidized PDMS surfaces by

Controlled Vesicle Self-Assembly in Continuous Two Phase Flow Microfluidic Channels

June 10, 2004
Author(s)
Andreas Jahn, Wyatt N. Vreeland, Laurie E. Locascio, Michael Gaitan
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 in a

Patterning Retinal Cells on Polyelectrolyte Multilayers

February 18, 2004
Author(s)
Darwin 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

Surface Characterization of Laser- Ablated Polymers Used for Microfluidics

February 15, 2002
Author(s)
D L. Pugmire, E A. Waddell, R Haasch, Michael J. Tarlov, Laurie E. Locascio
Fabrication of microfluidic devices by excimer laser ablation under different atmospheres may provide variations in polymer microchannel surface characteristics. The surface chemistry and electroosmotic (EO) mobility of polymer microchannels laser ablated
