Thorlabs is pleased to announce the release of a Surface-Enhanced Raman Spectroscopy (SERS) Substrate. Based on its proprietary textured surface technology, SERS in a non-destructive, highly sensitive ...

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 ...

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 ...

Light-matter interaction is one of the most fundamental ways to explore the physical world. While the reflection and refraction of light reveal the structural characteristics of matter, inelastic ...

The strength of a Raman signal is inversely proportional to the fourth power of the wavelength of the scattered light. In practical terms, this means that the longer the excitation wavelength used to ...

While Raman spectroscopy has been hugely successful in a number of domains of chemistry and materials science, 1-3 one of the main challenges with performing Raman measurements is the inherently weak ...

There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor ...
