Raman spectroscopy captures the effect when light partially scatters inelastically as it interacts with matter. The amounts of energy transferred between photons and molecules during this process correspond to specific molecular vibrations. Therefore, Raman spectroscopy is ideally suited for characterizing and identifying the chemical composition of various samples because the spectra provide a molecular “fingerprint.”

When highly complex samples such as microorganisms, cells, and tissue are investigated, all Raman active components — such as proteins, nucleic acids, carbohydrates, lipids, and other biomolecules — will…
