Fig. 4: Imaging of specific intracellular structures of a C. reinhardtii cell.
From: Infrared nanoscopy and tomography of intracellular structures

The nuclear region is visualized by AFM topography (a) with the scale bar showing 1 µm, sSNOM phase imaging at 1655 cm-1 (b) with the inset showing a line profile across a nuclear body, and sSNOM amplitude (c). The axoneme of the flagellum is similarly visualized using AFM topography (d) with the scale bar showing 100 nm, sSNOM phase imaging at 1656 cm-1 (e) and sSNOM amplitude (f), with the doublet microtubules (green marks) and the radial spokes (blue marks) of the flagellum.
