11. Terahertz spectroscopy of aqueous L-Proline in reverse micelles
Topic: Biological Physics
Published: 11/21/2008
Authors: Catherine C Cooksey, Edwin J Heilweil, Benjamin Greer
Abstract: A new method for obtaining room temperature terahertz (THz) absorption spectra of aqueous-phase biomolecules in the frequency range 1 THz to 21 THz (35 cm-1 to 700 cm-1) is reported. The spectrum for L-Proline was acquired by solvating the amino ac ...

12. THz Investigations of Condensed Phase Biomolecular Systems
Topic: Biological Physics
Published: 10/8/2008
Authors: Kevin O Douglass, Hailiang Zhang, Susan K. Gregurick, Karen M. Siegrist, David F Plusquellic
Abstract: Terahertz (THz) spectroscopic investigations of crystalline dipeptide nanotubes are discussed in the frequency region from 0.6 THz (2 cm-1) to 3 THz (100 cm-1). The THz region provides access to collective modes of biomolecular systems and is theref ...

13. Cholesterol/Phospholipid Interactions in Hybrid Bilayer Membranes
Topic: Biological Physics
Published: 5/25/2007
Authors: Dustin Levy, Kimberly A Briggman
Abstract: The interactions between cholesterol and saturated phospholipids in hybrid bilayer membranes (HBMs) were investigated using the interface-sensitive technique of vibrational sum frequency spectroscopy (VSFS). The unique sensitivity of VSFS to order/di ...

14. Characterization and Control of Lipid Layer Fluidity in Hybrid Bilayer Membranes
Topic: Biological Physics
Published: 1/31/2007
Authors: Neil A. Anderson, Lee J Richter, John C. Stephenson, Kimberly A Briggman
Abstract: The main gel-to-liquid-crystal (LC) phase transition temperature, Tm, of the distal lipid layer in hybrid bilayer membranes (HBMs) under water was investigated using vibrational sum frequency spectroscopy (VSFS). VSFS has unique sensitivity to order ...

15. Determination of Lipid Phase Transition Temperatures in Hybrid Bilayer Membranes
Topic: Biological Physics
Published: 9/9/2006
Authors: Neil A. Anderson, Lee J Richter, John C. Stephenson, Kimberly A Briggman
Abstract: The main gel to liquid crystal (LC) phase transition temperature, Tm, of the lipid monolayers in hybrid bilayer membranes (HBMs) was investigated using vibrational sum frequency spectroscopy (VSFS). The unique sensitivity of VSFS to probe order/diso ...
