21. Microfluidic Directed Self-Assembly of Liposome-Hydrogel Hybrid Nanoparticles
Published: 4/29/2010
Authors: Jennifer S. Hong, Samuel M Stavis, Silvia H. De Paoli Lacerda, Laurie E Locascio, Srinivasa R. Raghavan, Michael Gaitan
Abstract: We present a microfluidic method to direct the self-assembly of liposome-hydrogel hybrid nanoparticles. Our approach yields nanoparticle size distributions that are highly monodisperse and precisely controlled across a broad range relevant to the ta ...

22. Microfluidic and Nanofluidic Device Metrology
Published: 4/16/2010

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

24. Microfluidic-Directed Self-Assembly of Poly(N-Isopropylacrylamide) Lipobeads
Published: 10/9/2009
Authors: Jennifer S. Hong, Samuel M Stavis, Laurie E Locascio, Srinivasa R. Raghavan, Michael Gaitan

25. Nanofluidic Structures with Complex Three Dimensional Surfaces
Published: 3/31/2009
Authors: Samuel M Stavis, Elizabeth Strychalski, Michael Gaitan
Abstract: A fabrication process was developed to construct nanofluidic devices with complex three dimensional (3D) topographies. A single layer of grayscale photolithography enabled arbitrary and simultaneous control of numerous nanoscale etch depths in a fus ...

26. Single Molecule Analysis of Electrodynamically Stretched DNA in Nanochannels
Published: 10/13/2008
Authors: Samuel M Stavis, Christian H Reccius, John T Mannion, Larry P Walker, Harold G Craighead
Abstract: A rapid (~20 ms) and precise (~110 nm) analytical method is presented for stretching and interrogating single DNA molecules. Conformation, length, speed and fluorescence intensity measurements are obtained simultaneously. This confluence is a step ...

27. Non-planar nanofluidic devices for single molecule analysis fabricated using nanoglassblowing
Published: 6/17/2008
Authors: Elizabeth Strychalski, Samuel M Stavis, Harold G Craighead
Abstract: A method termed 'nanoglassblowing' is presented for fabricating integrated microfluidic and nanofluidic devices with gradual depth changes and wide, shallow nanochannels.  This method was used to construct fused silica channels with out-of-plane ...

28. Kilohertz Rotation of Nanomotors Propelled by Ultrasound, Traced by Microvortex Advection of Nanoparticles
Published: Date unknown
Authors: Andrew Lee Balk, Lamar O. Mair, Pramod Pappachan Mathai, Paul Nathan Patrone, Wei Wang, Suzanne Ahmed, Thomas Mallouk, James Alexander Liddle, Samuel M Stavis
Abstract: We measure the microvortical flows around gold nanorods propelled by ultrasound in water using polystyrene nanoparticles as optical tracers. We infer the rotational frequencies of such nanomotors assuming a hydrodynamic model of this interaction. In ...

29. Entropophoresis of Single Biomolecules Down a Nanofluidic Staircase
Published: 1/11/0011
Authors: Samuel M Stavis, Elizabeth A Strychalski, Michael Gaitan, Jon C Geist, Laurie E Locascio
