Lipids, proteins, and nucleic acids have closely associated water molecules (Bound water), which exhibit considerably different physical properties compared to bulk water. Here we investigate the possibility of resolving Raman spectra of the specific hydration shell of these biomolecules in intracellular regions using Raman imaging. Lipids and proteins + nucleic acids Raman spectral components resolved in the analysis showed associated water spectral features, which are uniquely different from that of bulk water. These spectral profiles agree with water spectral profile observed in the case of corresponding hydrated pure biomolecules. The results show the prospects of Raman imaging in examining intracellular hydration in biomolecules and its functional relation.
