Raman spectra acquired from cytoplasmic (A) and nuclear (B) regions of the same live HeLa cell that was incubated at 37°C for 60 h in a CoMoCAT DM-SWNT dispersion. The colored arrows in the optical micrographs denote the specific regions of the HeLa cell where spectra were acquired; spectra were also acquired from cell-free regions of the culture dish ~5 μm away from the nearest cell (dark-blue arrows). All spectra were normalized to the same intensity scale.
