A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2025.240027 , discusses tip-enhanced Raman scattering of glucose molecules.

Although Raman scattering is used commercially to analyze liquids and solids, applying it for the detection of low concentrations of gas requires a way to enhance the Raman scattering signal, ...

Sensitivity Issues: The intensity of Raman scattering is inherently weak, which can lead to sensitivity issues, especially when dealing with low concentrations of a substance. Advanced techniques like ...

Nonlinear Raman microscopy techniques, such as coherent anti-Stokes Raman scattering and stimulated Raman scattering, are widely used to provide chemical and spatial information. A third nonlinear ...

The technique is based on surface-enhanced Raman scattering (SERS), extending further the application of Raman methods and their molecular specificity to the problem of microplastics monitoring. The ...

Raman scattering. 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.

Surface enhanced Raman scattering monitoring tumor photodynamic therapy Peer-Reviewed Publication. Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS ...

The Raman signal 160 in FIG. 3 may be produced by coherent anti- Stokes Raman scattering (CARS) in which the pump and Stokes beams interact with a sample 150 to produce a Raman signal 160 at or ...
