“…The focused laser beams were overlapped under an angle of 15 • in a sample cuvette with a path length of 200 m, which is the optimum path length for these measurments [26]. At a scattering angle of 60 • , the scattered SF light was collimated with a plano-convex lens (f = 15 mm, Thorlabs LA1540-B) and then passed through two short wave pass filters (3rd Millenium, 3RD770SP and Thorlabs FES750).…”

“…Vibrational SFS spectra were measured, with equipment [69] and procedures [26] as previously described in detail using broadband infrared (IR) laser pulses centered at 2900 cm −1 (120 cm −1 FWHM bandwidth) and visible (VIS) pulses at 800 nm (12 cm −1 FWHM) at a repetition rate of 1 kHz. The focused laser beams were overlapped under an angle of 15 • in a sample cuvette with a path length of 200 m, which is the optimum path length for these measurments [26].…”

“…Since the scattering experiments are performed in transmission geometry using a 10-1000 m thick cuvette, the IR pulses will lose their intensity as they travel through the dispersion. The combined absorption and scattering effects [26] limit in this case the accessible spectral window to the region above ∼2670 cm −1 . Nevertheless, this limited window can still provide us information about the interfacial vibrational modes of the part of the water molecules that have a vibrational SF active mode along the surface normal and hence the interfacial structure of water.…”

“…Small Langmuir trough Nanodroplets This restriction is much reduced in nonlinear light scattering experiments performed on a nanodroplet system [26]: A nanodroplet dispersion can be prepared in situ using only a small volumes of chemicals.

In the past five years the Laboratory for fundamental BioPhotonics (LBP) has worked on developing new technology that can access the molecular structure and nanoscale properties of buried aqueous interfaces and aqueous solutions. Using these methods a better understanding of the important role that water plays in (nanoscale and interfacial) processes can be obtained. These processes include the long-range interaction of ions with water, structural and charge anomalies of the hydrophobic/aqueous interface, the formation and stabilization of amphiphilic aqueous droplet interfaces, the formation and molecular properties of the electric double layer, as well as membrane structure and hydration. The result of our work on these themes is summarized for this special issue article.

Optimizing protocols so that the structure of the collagen fibers in the extracellular matrix remains intact during the decellularization process requires techniques with high structural sensitivity, especially for the surface region of the collagen fibers. Here, we demonstrate that vibrational sumfrequency scattering (SFS) spectroscopy in the protein-specific amide I region provides vibrational spectra and scattering patterns characteristic of protein fiber networks self-assembled in vitro from collagen type I, which are kept in aqueous environments during the analysis. At scattering angles away from the phase-matched direction, the relative strengths of the various polarization combinations are highly reproducible, and changes in their ratios can be followed in real-time during exposure to sodium dodecyl sulfate surfactant solutions. For the fibers in this work, a scattering angle of about 22° provided specificity for the surface region of the fibers, as it allowed monitoring of immediate structural changes during the surfactant exposure. With further development, we hypothesize that the information from SFS characterization of collagen fibers may complement information from other techniques with sensitivity to overall structure, such as second-harmonic generation imaging and infrared spectroscopy, and provide a more complete understanding of fiber molecular structures and interactions during exposure to various environments and conditions.
