Molecular bonding and interactions at aqueous surfaces as probed by vibrational sum frequency spectroscopy.
Aqueous surfaces and interfaces are important in many physical, chemical, and biological processes in our world. The adsorption, dissolution, and reaction of atmospheric gases at the surfaces of atmospheric aerosols and oceanic waters play a key role in the composition of our atmosphere and the sustainability of plant and animal species in land waters. The transport and exchange of ions and sol...
متن کاملKinetics of ultraviolet and plasma surface modification of poly(dimethylsiloxane) probed by sum frequency vibrational spectroscopy.
In numerous applications in microfluidics, cell growth, soft lithography, and molecular imprinting, the surface of poly(dimethylsiloxane) (PDMS) is modified from a hydrophobic methyl-terminated surface to a hydrophilic hydroxyl-terminated surface. In this study, we investigated molecular structural and orientational changes at the PDMS-air interface in response to three commonly used surface mo...
متن کاملChiral Vibrational Structures of Proteins at Interfaces Probed by Sum Frequency Generation Spectroscopy
We review the recent development of chiral sum frequency generation (SFG) spectroscopy and its applications to study chiral vibrational structures at interfaces. This review summarizes observations of chiral SFG signals from various molecular systems and describes the molecular origins of chiral SFG response. It focuses on the chiral vibrational structures of proteins and presents the chiral SF...

متن کاملNanoporous silica-water interfaces studied by sum-frequency vibrational spectroscopy.
Using sum-frequency vibrational spectroscopy, we found that water structure at nanoporous silica/water interfaces depended on the nanoporous film structure. For a periodic, self-assembled nanoporous film with monosized 2 nm pores occupying 20% of the top surface area, the surface vibrational spectrum was dominated by water in contact with silica, bare or covered by silane, at the top surface. I...
