Structural analysis of intrinsically unstructured proteins using Raman optical activity
A major obstacle in the structural analysis of intrinsically unstructured proteins (IUPs), at least from a classical biological perspective, is precisely that: lack of structure. While the dynamic nature of IUPs makes crystallographic studies virtually impossible, even solution based NMR studies of this group of proteins are difficult, due to the fast, fluid changes in back bone torsion angles....
متن کاملOptical Communication Noise Rejection Using Correlated Photons
This paper describes a completely new way to perform noise rejection using a two-photon sensitive detector and taking advantage of the properties of correlated photons to improve an optical communications link in the presence of uncorrelated noise. In particular, a detailed analysis is made of the case where a classical link would be saturated by an intense background, such as when a satellite ...
متن کاملMagnetic Raman optical activity and Raman electron paramagnetic resonance
All molecules in a magnetic field parallel to the incident light beam show a small difference in the intensity of Raman scattering at 900 in right and left circularly polarized incident light. The most interesting effects occur in vibrational resonance Raman scattering from odd—electron transition metal halides, and in pure electronic resonance Raman scattering from both odd— and even—electron ...
متن کاملOptical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods
An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...
متن کاملOptical activity in twisted solid-core photonic crystal fibers.
In this Letter we show that, in spectral regions where there are no orbital cladding resonances to cause transmission loss, the core mode of a continuously twisted photonic crystal fiber (PCF) exhibits optical activity, and that the magnitude of the associated circular birefringence increases linearly with twist rate and is highly reproducible. In contrast to previous work on twist-induced circ...
