From: Single-walled carbon nanotube interactions with HeLa cells
Representative Raman spectra acquired from five different live HeLa cells that were incubated at 37°C in CoMoCAT DM-SWNT dispersions for 12, 24, 36, 48, and 60 h. All spectra were normalized to the same intensity scale. The G-band intensities increased in a linear fashion (R2 = 0.932) over the course of 12–60 h (n = 8 cells analyzed at each time point).
