Microfluidic DNA Analysis Systems for Forensic Applications

July 18, 2008
Author(s)
Michael Gaitan, Jayna J. Shah, Darwin Reyes-Hernandez, Pierre-Alain Auroux, Jon Geist, Laurie E. Locascio, Wyatt N. Vreeland, David J. Ross, Peter Vallone, Paul Smith, Nicole Morgan, Tom Pohida, John Kakareka, Annelise Barron
This report summarizes the NIST effort on microfluidic DNA analysis systems for forensic applications sponsored by the National Institute of Justice. Currently emerging microfluidics-based forensic systems are implemented in silica (glass) because the

Counter-Flow Gradient Electrofocusing

February 1, 2007
Author(s)
Jonathan G. Shackman, David J. Ross
Counter-flow gradient electrofocusing methods are methods whereby a combination of electrophoresis and a bulk solution counter-flow is used to accumulate or focus analytes at stationary points along a separation column. This review first describes the

Scanning Temperature Gradient Focusing

August 2, 2006
Author(s)
S J. Hoebel, K M. Balss, Barbara J. Jones, C Malliaris, Matt S. Munson, Wyatt N. Vreeland, David J. Ross
Temperature gradient focusing (TGF) is a recently developed technique for the simultaneous concentration and electrophoretic separation of ionic analytes in microfluidic channels. One drawback to TGF as it has previously been described is the limited peak

Micellar Affinity Gradient Focusing

February 25, 2004
Author(s)
K M. Balss, P B. Howell, David J. Ross
This report describes a novel method for the concentration and separation of neutral and/or hydrophobic analytes based on a combination of the analytes partitioning into a micellar phase and their electrophoretic mobility. This method of simultaneous
