Figure 1.
Raman spectra of 1) trehalose, 2) dextran, 3) DMSO, 4) cytochrome c from cell, 5) ice with corresponding Raman images, and 6) Raman spectra of Jurkat cell cryopreserved in 10% DMSO. Images on the right are rendered based on the specific signal on the left, and light microscopy images are given as a reference. All cells imaged are alive. To see this figure in color, go online.
