41. 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 ...

42. 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 ...

47. Conformational Analysis of the Jet-Cooled Peptide Mimetic Ethylacetamidoacetate from Torsion-Rotation Spectra
Published: 9/1/2003
Authors: R J. Lavrich, Angela R Hight Walker, David F Plusquellic, I Kleiner, R D. Suenram, Jon Torger Hougen, Gerald T Fraser
Abstract: Rotational spectra of two conformers of the dipeptide mimetic, ethyl acetamidoacetate, were measured in a molecular beam using a Fourier-transform microwave spectrometer. In each conformer, internal rotation of the acetyl methyl group gives rise to ...

50. Experimental Studies of Peptide Bonds: Identification of the C^d7^^ueq^ Conformation of the Alanine Dipeptide Analog N-Acetyl-Alanine N'-Methylamide From Torsion-Rotation Interactions
Published: 1/1/2003
Authors: R J. Lavrich, David F Plusquellic, R D. Suenram, Gerald T Fraser, Angela R Hight Walker, M J Tubergen
Abstract: Rotational spectra of the bio-mimetic molecule, alanine dipepitide and the double ^u15^N(^u15^N^d2^) isotopomer have been observed using a pulsed-molecular-beam Fourier transform microwave spectrometer. The spectra reveal large tunneling splittings ...
