Fig. 1. High wavenumber spectral response to lipid altering drugs. Average Raman spectra from the high wavenumber spectral region from all spectra extracted from cell regions of three different Raman maps were compared between PC3 and PNT2 control (DMSO) cells (a); PC3 cells treated with DMSO (control), or a lipid altering drug (b); and PNT2 cells treated with DMSO (control), or a lipid altering drug (c). Cells were mapped using 532 nm, 0.5 s acquisition, 15 mW laser power, 1 μm step size in x and y and a spectral center of 3000 cm–1.
