A new imaging technology can distinguish cancerous tissue from healthy cells by detecting ultra-weak light signals. It relies ...

The ability of Raman spectroscopy to identify molecular-level spectral fingerprints has made it an attractive route to diagnostic information and identification of early-stage tumors, especially in ...

Abstract: Raman spectroscopy (RS) is a label-free molecular vibrational spectroscopy technique that is able to identify the molecular fingerprint of various samples making use of the inelastic ...

Using a diamond crystal measuring just a few millimeters across in a carefully designed cavity, they tested a deliberately "noisy" input beam with linewidth exceeding 10 MHz. Their Raman scattering ...

The Trump administration is planning to close a small, obscure laboratory whose work undergirds everything from microchip manufacturing to nuclear fusion. The Atomic Spectroscopy Group at the National ...

Abstract: Various improved Raman techniques such as coherent, resonant, and surface-enhanced Raman scattering, have been reported to boost Raman signals over spontaneous Raman spectroscopy (RS).

Raman spectroscopy is a non-destructive analytical technique used in multiple industries. Detailed material information such as molecular interactions, molecular structure, crystallinity, and phase ...

Raman spectroscopy is increasingly used for polymer characterization because it is non-destructive, requires no sample preparation, and produces data in seconds. It is also simple for the user; even ...

Hyperspectral unmixing methods are essential to exploit the capabilities of Raman spectroscopy for nondestructive, unbiased chemical characterization in a wide array of domains, from biology, ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...
