11. Magnetic-field-induced assemblies of cobalt nanoparticles
Published: 1/1/2005
Authors: Guangjun Cheng, Angela R Hight Walker, Gerald T Fraser, D B Romero
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=103692

12. Surface Enhanced Raman Spectroscopy in a Microfluidic Device
Published: 2/1/2004
Authors: D Dunmire, D B Romero, Guangjun Cheng, Angela R Hight Walker
Abstract: Surface enhanced Raman spectroscopy (SERS) is employed to study the solution phase vibrational structure of molecules on gold and silver colloids. Gold and silver colloids show large enhancement factors enabling sub-micromolar detection limits. Using ...

13. Synthesis of Bioconjugated Magnetic Nanoparticles for Magneto-Raman Study
Published: 2/1/2004
Authors: Guangjun Cheng, D B Romero, D Dunmire, Angela R Hight Walker
Abstract: We are investigating the effects of an externally applied magnetic field on the structure and magnetic properties of biomolecules (DNA and proteins). A newly constructed, magneto-Raman confocal microscope system couples a cryo-magnet to a triple grat ...
