Deuterium-labeled SRS Omage of a Protein, Lipid and DNA Molecule (image) Columbia University Share Print E-Mail Caption As living cells absorb heavy water, deuterium is incorporated into newly made proteins, lipids and DNA. When the researchers aimed the light of a stimulated Raman scattering (SRS) microscope at a single cell, each of the macromolecules above could be identified within.
