Raman spectroscopy is a reliable quantitative and qualitative technique used to examine molecular or material samples. Raman spectroscopy’s sensitivity to a sample’s vibrational structure makes it ...

When light reflects off a surface, not all of it reflects off at the same wavelength; some photons impart a portion of their ...

Raman spectroscopy enables real-time bioreactor monitoring of glucose and lactate without breaching the sterile boundary.

Tip-Enhanced Raman Spectroscopy (TERS) leverages a finely sharpened metallic probe to concentrate incident light into a plasmonic near-field at the apex of the tip, thereby amplifying Raman scattering ...

Visualization of Tip-Enhanced Raman Spectroscopy (TERS): This diagram illustrates the interaction of a laser beam with a sample surface through a sharp metallic tip. The red laser light excites the ...

(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...

Laser lights are usually employed for the Raman spectroscopic analysis. The photons emitted by the laser light are absorbed by the sample, temporarily entering a non-stationary, exceedingly brief ...

A research team led by Prof. Fang Yonghua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed and systematically optimized a novel parabolic mirror ...

Raman spectrography uses the Raman scattering of photons from a laser or other coherent light beam to measure the vibrational state of molecules. In chemistry, this is useful for identifying molecules ...
