Jetting Flow of a Shear Banding Fluid

November 20, 2016

Author(s)

Paul NMN Salipante, Charles A. Little, Steven D Hudson

In this video we show the jetting behavior of a shear banding worm-like micelle solution in microfluidic flows. The jetting behavior is characterized by a self-contained portion of the channel where the flow velocity is greater than the surroundings. We

On-wafer Magnetic Resonance of Magnetite Nanoparticles

May 11, 2015

Author(s)

Charles A. Little, Stephen E. Russek, James C. Booth, Pavel Kabos, Robert J. Usselman

Magnetic resonance measurements of ferumoxytol and TEMPO were made using an on-wafer transmission line technique with a vector network analyzer, allowing for broadband measurements of small sample volumes (4 nl) and a small numbers of spin (1 nmole). On

Dielectrofluidics for Electronic-Based Chemical and Particle Analysis

August 18, 2014

Author(s)

James C. Booth, Spencer T. Egan, Charles A. Little, A Padilla, Yu Y. Wang, Nathan D. Orloff

The interactions of electromagnetic fields with matter are described by means of the polarization and magnetization of the material under study. Analogous to the way that magnetofluidics seeks to exploit magnetic interactions for sensing and manipulating

Microfluidic Platform for Magnetic Nanoparticle Trapping and Detection

July 15, 2013

Author(s)

Charles A. Little, John Pellegrino, Stephen E. Russek

We evaluate giant magnetoresistance (GMR) sensors to trap and count small concentrations of magnetic nanoparticles (MNPs) within microfluidic flow. The device presented in this paper takes the novel approach of capturing and detecting MNPs utilizing the
