 On the other hand, resonance Raman imaging of single-cell algae at 532 nm (green) can specifically probe the carotenoid distribution within a cell by a using low laser power of ~5 µW and only 100 ms acquisition time.Raman scattering, specifically tip-enhanced Raman spectroscopy, produces high resolution hyperspectral images of single molecules  atoms, and DNA.Raman scattering is polarization sensitive and can provide detailed information on symmetry of Raman active modes.
