Light interacts with matter in various ways. CRS microscopy relies on a specific type of light-matter interaction known as Raman scattering. When light impinges on a molecule, it can inelastically scatter, meaning the molecule absorbs some energy and re-emits light at a slightly different frequency. This shift in frequency, known as the Raman shift, is unique to each molecule and acts as its spectral fingerprint.

Light interacts with matter in various ways. CRS microscopy relies on a specific type of light-matter interaction known as Raman scattering. When light impinges on a molecule, it can inelastically scatter, meaning the molecule absorbs some energy and re-emits light at a slightly different frequency. This shift in frequency, known as the Raman shift, is unique to each molecule and acts as its spectral fingerprint. CRS microscopy leverages this principle to generate detailed chemical maps of a sample. By focusing a laser beam onto the sample and analyzing the scattered light, researchers can identify the specific molecules present based on their characteristic Raman shifts. Unlike traditional Raman spectroscopy, CRS microscopy employs coherent light sources, allowing for enhanced signal-to-noise ratio and deeper tissue penetration.
