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. 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. Centroid and Orientation Precision of Localization Microscopy
Published: 3/11/2016
Authors: Craig Dyer McGray, Craig Robert Copeland, Samuel M Stavis, Jon C Geist
Abstract: The concept of localization precision, which is essential to localization microscopy, is formally extended from optical point sources to microscopic rigid bodies. Measurement functions are presented to calculate the planar position, orientation, and ...

5. 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 ...

6. 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 ...

7. 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 ...

8. 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 ...

9. Engineered Microfluidic and Nanofluidic Device Metrology
Published: 3/22/2010
Author: Samuel M Stavis
