Conformational changes in quadruplex oligonucleotide structures probed by Raman spectroscopy

Quadruplex structures are higher order structures formed by guanine-rich oligonucleotides. In the present study, temperature-induced conformational changes in the quadruplex structures of aptamers and other guanine-rich oligonucleotides are probed by Raman spectroscopy. In particular, dramatic changes in the fingerprint region are observed in the spectra of thrombin binding aptamer at higher te...

Multicomponent blood analysis by near-infrared Raman spectroscopy.

We demonstrate the use of Raman spectroscopy to measure the concentration of many important constituents (analytes) in serum and whole blood samples at physiological concentration in vitro across a multipatient data set. A near-infrared (830-nm) diode laser generates Raman spectra that contain superpositions of Raman signals from different analytes. Calibrations for glucose, cholesterol, urea, ...

Structure and dynamics of the DNA-binding protein HU of B. stearothermophilus investigated by Raman and ultraviolet-resonance Raman spectroscopy.

The histone-like protein HU of Bacillus stearothermophilus (HUBst) is a 90-residue homodimer that binds nonspecifically to B DNA. Although the structure of the HUBst:DNA complex is not known, the proposed DNA-binding surface consists of extended arms that project from an alpha-helical platform. Here, we report Raman and ultraviolet-resonance Raman (UVRR) spectra diagnostic of subunit secondary ...

The In-Plane Anisotropy of WTe2 Investigated by Angle-Dependent and Polarized Raman Spectroscopy

Tungsten ditelluride (WTe2) is a semi-metallic layered transition metal dichalcogenide with a stable distorted 1T phase. The reduced symmetry of this system leads to in-plane anisotropy in various materials properties. We have systemically studied the in-plane anisotropy of Raman modes in few-layer and bulk WTe2 by angle-dependent and polarized Raman spectroscopy (ADPRS). Ten Raman modes are cl...
