Probing cavitand-organosilane hybrid bilayers via sum-frequency vibrational spectroscopy.

In situ molecular level studies on membrane related peptides and proteins in real time using sum frequency generation vibrational spectroscopy.

Sum frequency generation (SFG) vibrational spectroscopy has been demonstrated to be a powerful technique to study the molecular structures of surfaces and interfaces in different chemical environments. This review summarizes recent SFG studies on hybrid bilayer membranes and substrate-supported lipid monolayers and bilayers, the interaction between peptides/proteins and lipid monolayers/bilayer...

Probing the Molecular Conformation of Self-Assembled Monolayers at Metal/Semiconductor Interfaces by Vibrational Sum Frequency Generation Spectroscopy

Single Lipid Bilayers Constructed on Polymer Cushion Studied by Sum Frequency Generation Vibrational Spectroscopy.

Planar solid supported single lipid bilayers on mica, glass, or other inorganic surfaces have been widely used as models for cell membranes. To more closely mimic the cell membrane environment, soft hydrophilic polymer cushions were introduced between the hard inorganic substrate and the lipid bilayer to completely avoid the possible substrate-lipid interactions. In this article, sum frequency ...

Broadband vibrational sum frequency generation spectroscopy of a liquid surface.

An important advance in surface science has been the evolution of sum frequency generation to the application of studying surface structure and chemistry of liquid surfaces at the molecular-level by probing the vibrational signatures of surface molecules. Recently, broad-bandwidth sum frequency generation (BBSFG) spectroscopy has become an important tool for investigating gas-solid interfaces. ...

Dependence of antimicrobial selectivity and potency on oligomer structure investigated using substrate supported lipid bilayers and sum frequency generation vibrational spectroscopy.

Sum frequency generation (SFG) vibrational spectroscopy was used to study interactions between solid-supported lipid bilayers mimicking microbial and erythrocyte cellular membranes and synthetic antimicrobial arylamide oligomers named 2, 3, and 4, designed with the facial amphiphilicity common to naturally occurring antimicrobial peptides. The three compounds have the same backbone structure bu...
