"Our technique uses stimulated Raman scattering, where the laser stimulates much higher frequency vibrations in the material, and is thousands of times more effective at narrowing linewidth." ...

Detecting nanoscale plastic pollutants in the environment is a continuing challenge, and their presence is commonly only estimated rather than measured directly. A project at Vienna's TU Wien has now ...

Raman spectroscopy is a non-destructive analytical method that generates complex information about the phase, chemical structure and crystallinity of sample matter. A range of molecular interactions ...

Researchers have developed a new compact Raman imaging system that is sensitive enough to differentiate between tumor and normal tissue. The system offers a promising route to earlier cancer detection ...

Seeing chemistry unfold inside living cells is one of the biggest challenges of modern bioimaging. Raman microscopy offers a powerful way to meet this challenge by reading the unique vibrational ...

Raman imaging techniques are used to obtain information about the molecular vibrations and crystal structure of a sample. Image pixels are used to acquire a complete spectrum, which is subsequently ...

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 ...

In confocal Raman microscopy, a Raman spectrometer is coupled to a standard optical microscope, which leads to a high magnification of the sample and subsequent Raman analysis. Combining Raman ...
