1. Cellular Immobilization within Microfluidic Microenvironments: Dielectophoresis with Polyelectrolyte Multilayers
Published: 10/25/2006
Authors: Samuel P. Forrey, Darwin R Reyes-Hernandez, Michael Gaitan, Laurie E Locascio
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=32513

2. Dielectrophoretic Cell Capture on Polyester Membranes
Published: 4/2/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: A new system for dielectrophoretic cell capture on porous polyester (PET) membranes is presented. Conventional photolithographic techniques were used to fabricate gold microelectrodes on a PET membrane. We characterized these electrodes to proof th ...

3. Dielectrophoretic Trapping of P19 Cells on Indium Tin Oxide based Microelectrode Arrays
Published: 11/8/2013
Authors: Aveek Gangopadhyay, Saugandhika Minnikanti, Darwin R Reyes-Hernandez, Mulpuri V. Rao, Nathalia Peixoto
Abstract: A microfabricated device comprised of a microelectrode array (MEA) and a microfluidic channel is presented here for the purpose of trapping cells using positive dielectrophoresis (DEP). Transparent indium tin oxide (ITO) electrodes are patterned in a ...

4. Electrical Manipulation of Gold Nanoparticles for Microfluidic Applications
Published: 10/16/2008
Authors: Darwin R Reyes-Hernandez, Geraldine I. Mijares, Kimberly A Briggman, Jon C Geist, Michael Gaitan
Abstract: An electrical method to trap and release gold nanoparticles to and from the surface of alkanethiol-modified gold electrodes is presented. When a positive bias versus a Ag/AgCl reference electrode was applied to gold electrodes, negatively-charged go ...

5. Enabling Long-Term Dielectrophoretic Actuation for Cell Manipulation and Analysis in Microfluidic Biochips
Published: 10/7/2012
Author: Darwin R Reyes-Hernandez
Abstract: An approach that combines not only the cell manipulation capabilities of dielectrophoresis (DEP), but also the conditions to promote appropriate cell function during long-term experiments is presented. The integration of a hybrid cell adhesive mater ...

6. Fabrication of Microelectrodes on Polyester Membranes for Dielectrophoretic Cell Capture
Published: 6/18/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: We present a new system for cell capturing on permeable polyester (PET) membranes using dielectrophoretic forces. For the first time gold microelectrodes were fabricated on PET membranes using conventional photolithographic techniques. Their charac ...

7. Facilitating the Culture of Mammalian Nerve Cells with Polyelectrolyte Multilayers
Published: 5/19/2006
Authors: Samuel P Forry, Darwin R Reyes-Hernandez, Michael Gaitan, Laurie E Locascio
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=32339

8. Fast and High Efficient Microfluidic PCR By Microwave Dielectric Heating
Published: 10/15/2007
Authors: Pierre-Alain Auroux, Darwin R Reyes-Hernandez, Jayna J Shah, Michael Gaitan
Abstract: We report 100% yield and 40% reaction-time reduction for on-chip DNA amplification using microwave dielectric heating. A passivation protocol has also been developed to suppress the inhibition of PCR in PMMA chips used with a temperature sensor. We f ...

9. GENERATING CELL CO-CULTURES BY RAPID CELL ADHESION ON OPPOSITE SIDES OF POLYESTER MEMBRANES
Published: 10/28/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: A cell co-culture was generated on opposite sides of a permeable polyester membrane (PET) membrane by combining dielectrophoretic (DEP) and electrostatic forces to hold cells against gravity in a multilayer microfluidic device (Figure 1). HepG2 cell ...
