Fig. 4: Results of multimodal imaging of HeLa cells using t-SPESI.

Fluorescence (a, e), ion (b, f), topographic (c, g), and amplitude (d, h) images of mCAT and cGCS cells. i, j Section profiles of topographic and amplitude images of mCAT and cGCS cells, respectively. The positions of the cross sections are indicated in the topographic and amplitude images. k, l Histograms of the signal intensities of the topographic and amplitude images of mCAT and cGCS cells, respectively.
