Two-dimensional (2D) optical spectroscopy utilizing multiple ultrafast coherent laser pulses
in the infrared or UV-vis frequency range has been used to study protein structure and …

Molecular aggregates are abundant in nature; they form spontaneously in concentrated
solutions and on surfaces and can be synthesized by supramolecular chemistry techniques …

The infrared spectrum (IR) characteristic peaks of amide I, amide II, and amide III bands are
marked as amide or peptide characteristic peaks. Through the nuclear magnetic resonance …

Peptides and proteins are naturally chiral molecular systems so that sensing their structure
and conformation with chirality-based spectral methods is an obvious and long-used …

In this work, we demonstrate the feasibility to collect off-electronic resonance chiral sum
frequency generation (SFG) vibrational spectra from interfacial proteins and peptides at the …

Soluble oligomers of the amyloid-β (1-42)(Aβ42) peptide, widely considered to be among
the relevant neurotoxic species involved in Alzheimer's disease, were characterized with a …

An empirical correction to amide group vacuum force fields is proposed in order to account
for the influence of the aqueous environment on the CvO stretching vibration amide I. The …

Biomineralization occurs in aqueous environments. Despite the ubiquity and relevance of
CaCO3 biomineralization, the role of water in the biomineralization process has remained …

A series of β-hairpin peptides based on variations of the TrpZip2 sequence,
SWTWENGKWTWK, of Cochran and co-workers were studied using electronic circular …

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 …
