Proteins at interfaces play important roles in cell biology, immunology, bioengineering, and
biomimetic material design. Many biological processes are based on interfacial protein …

Proteins exhibit structural fluctuations over decades of time scales. From the picosecond
side chain motions to aggregates that form over the course of minutes, characterizing protein …

Ultrafast two-dimensional infrared spectroscopy (2D IR) has been advanced in recent years
toward measuring signals from only a monolayer of sample molecules at solid–liquid and …

Multidimensional ultrafast spectroscopies are one of the premier tools to investigate
condensed phase dynamics of biological, chemical and functional nanomaterial systems. As …

This paper presents an overview of the principal structural and dynamics characteristics of
reverse micelles (RMs) in order to highlight their structural flexibility and versatility, along …

Determining the secondary and tertiary structures of proteins at aqueous interfaces is crucial
for understanding their function, but measuring these structures selectively at the interface is …

Abstract Infrared (IR)-visible (Vis) sum frequency generation (SFG) is a second-order
nonlinear optical process which is forbidden in centrosymmetric bulk media or isotropic …

Sum frequency generation vibrational spectroscopy (SFG-VS) has become one of the most
appealing technologies to characterize molecular structures at interfaces. In this focal point …
