MiROM micrographs at 2853 cm-1 of (a) PreBAT, (b) 3T3-L1, and (c) HeLa cells after background subtraction. The FOV for a and b is 125 µm x 125 µm while the FOV for c is 150 µm x 150 µm, scale bars: 25 µm. The contrast profile at the indicated dashed line on each cell is plotted below the regarding micrograph. The CNR in PreBAT is 22:1, in 3T3-L1 is 17:1, and in HeLa cells is 7:1. The units in the contrast bars are in mV. Images a-c are representative of three independent experiments.
