Figure 1. Plasmonic imaging of intracellular organelle dynamics in live cell.

Figure 1

(a) Schematic diagram of plasmonic imaging setup for imaging intracellular processes. (b, c) Transmitted (b) and plasmonic (c) images of single SH-EP1 cell. (d) A representative image of intracellular organelles after subtracting the first frame, where the white arrows indicate the intracellular organelles. (e, f) Zoom-in images of another plasmonic image after subtracting the first frame (e) and epi-fluorescence (f) labeled with MitoTracker® in region marked by orange boxes in (d). Red arrows indicate common features of plasmonic images and fluorescence. Blue arrows indicate fluorescence-only features. Note the blurry of the fluorescence image of (f) is affected by the gold film. Scale bar: (b–d) 25 µm; (e, f) 5 µm.
