2. User's Guide for RM 8096 and 8097: The MEMS 5-in-1, 2013 Edition
Series: Special Publication (NIST SP)
Report Number: 260-177
Published: 2/15/2013
Authors: Janet M Cassard, Jon C Geist, Theodore Vincent Vorburger, David Thomas Read, Michael Gaitan, David G Seiler
Abstract: The Microelectromechanical Systems (MEMS) 5-in-1 is a reference device sold as a NIST Reference Material (RM) that contains MEMS test structures on a test chip. The two RM chips (8096 and 8097) provide for both dimensional and material property ...

3. MEMS Kinematics by Super-Resolution Fluorescence Microscopy
Published: 9/28/2012
Authors: Craig Dyer McGray, Samuel M Stavis, Joshua Giltinan, Eric Eastman, Samara L. Firebaugh, Jenelle Piepmeier, Jon C Geist, Michael Gaitan
Abstract: Super-resolution fluorescence microscopy is used for the first time to study the nanoscale kinematics of a MEMS device in motion across a surface. A device under test is labeled with fluorescent nanoparticles that form a microscale constellation of n ...

4. The MEMS 5-in-1 Reference Materials (RM 8096 and 8097)
Published: 3/21/2012
Authors: Janet M Cassard, Jon C Geist, Michael Gaitan, David G Seiler
Abstract: The MEMS 5-in-1 Reference Material (RM) contains test structures for five standard test methods on one test chip, so companies can compare their in-house measurements taken on the RM with NIST measurements, thereby validating their use of the documen ...

5. Quantitative Measurements of the Size Scaling of Linear and Circular DNA in Nanofluidic Slitlike Confinement
Published: 2/14/2012
Authors: Elizabeth A Strychalski, Jon C Geist, Michael Gaitan, Laurie E Locascio, Samuel M Stavis
Abstract: Quantitative size measurements of single linear and circular DNA molecules in nanofluidic slitlike confinement are reported. A novel experimental method using DNA entropophoresis down a nanofluidic staircase implemented comprehensive variation of sl ...

6. 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 ...

7. MEMS
Published: 1/12/2012
Author: Michael Gaitan
Abstract: Micro-Electro-Mechanical Systems (MEMS) are devices that are fabricated using techniques similar to those used for integrated circuits (ICs) to create micrometer-sized mechanical structures (suspended bridges, cantilevers, membranes, fluid channels ...

8. 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 ...

9. Hybrid Cell Adhesive Material for Instant Dielectrophoretic Cell Trapping and Long Term Cell Function Assessment
Published: 8/16/2011
Authors: Darwin R Reyes-Hernandez, Jennifer S. Hong, John T Elliott, Michael Gaitan
Abstract: We present the development and evaluation of an engineered hybrid cell adhesive surface for instant dielectrophoretic trapping and patterning of cells in a microfluidic device. This work demonstrates that a hybrid cell adhesive material (hCAM) prepar ...

10. Trapping and Release of Citrate-Capped Gold Nanoparticles
Published: 8/1/2011
Authors: Darwin R Reyes-Hernandez, Geraldine I. Mijares, Brian Joseph Nablo, Kimberly A Briggman, Michael Gaitan
Abstract: An electrical method to trap and release charged gold nanoparticles on and from the surface of alkanethiol self-assembled-monolayer (SAM) modified gold electrodes is presented. Gold nanoparticle (GNP) coated electrodes were formed by immersing amine ...
