CERS allows us to measure the composition, size and refractive index of a particle. From the spontaneous Raman signature, changes in chemical composition can be monitored from changing intensities in ...
In complicated biomolecules, aromatics and chromophores resonate leading to a considerably amplified Raman signature in comparison to the analogous measurements in the spectrum’s visible region.
Raman spectroscopy, which can be used to identify molecules based on signature vibrational frequencies of chemical bonds following excitation by a laser, offers a label-free alternative.
