Fig. 4 a) STED-FLIM imaging (top-left) and its corresponding photon count image (bottom-right) of LDs in HeLa cells by STED-FLIM nanoscopy. Scale bar: 5 µm. b) STED and CLSM imaging in the field of view of ROI 7 in (a) and Figure S31. λex = 488 nm, λem = 650–725 nm, and λSTED = 775 nm. c) Zoomed-in map of (a) and Figure S31 in ROI 8. d) STED-FLIM image of LDs, the magnified image of the white dotted square is shown in Figure 5c. e) Fluorescence lifetime changes recorded along the white dotted line in (d). f) Fluorescence lifetime spectrums are recorded corresponding to positions (1, 2, 3, 4, and 5) in (d). ROS scavenger UA (50 µM) was added to avoid probe-induced lipid oxidation under light conditions.
