1. A Glowing Future for Lab on a Chip Testing Standards
Published: 6/28/2012
Author: Samuel M Stavis
Abstract: Testing standards are more fundamental from a metrological perspective and less controversial from an industrial perspective than product standards, representing a path of less resistance towards the standardization and commercialization of lab on a ...

2. A localized transition in the size variation of circular DNA in nanofluidic slitlike confinement
Published: 4/15/2013
Authors: Elizabeth A Strychalski, Samuel M Stavis, Jon C Geist
Abstract: We report strong evidence for a localized transition in the size variation of circular DNA between strong and moderate regimes of slitlike confinement. A novel and rigorous statistical analysis was applied to our recent experimental measurements ...

3. Accurate optical analysis of single molecule entrapment in nanoscale vesicles
Published: 1/1/2010
Authors: Joseph E. (Joseph E.) Reiner, Andreas Jahn, Samuel M Stavis, Michael J Culbertson, Wyatt N Vreeland, Daniel L Burden, Jon C Geist, Michael Gaitan
Abstract: We present a non-destructive method to characterize low analyte concentrations in nanometer scale lipid vesicle formulations. Our method is based on the application of fluorescence fluctuation analysis (FFA) and multi-angle laser light scattering (M ...

4. Characterization of Electrothermal Actuation with Nanometer and Microradian Precision
Published: 6/21/2015
Authors: Craig Robert Copeland, Craig Dyer McGray, Jon C Geist, Vladimir A Aksyuk, Samuel M Stavis
Abstract: A recently introduced particle-tracking method was used to measure the single motion cycles of an electrothermal actuator with nanometer and microradian precision. Driving the actuator with a low-noise input induced deterministic motion that was per ...

5. 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 ...

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. Dimensional Reduction of Duplex DNA Under Nanofluidic Slit Confinement
Published: 8/19/2015
Authors: Luis Fernando Vargas Lara, Jack F Douglas, Samuel M Stavis, Elizabeth A Strychalski, Jon C Geist, Brian Joseph Nablo
Abstract: There has been much recent interest in the dimensional properties of duplex DNA under nanoscale confinement conditions as a problem of fundamental interest in both technological and biological fields. This has led to a series of measurements by f ...
