a–c Autofluorescence image of NADH in yeast cells under UV structured illumination with D1, D2, and D3 orientations, respectively. The insert is a three times magnified zoom of the area defined by the orange dotted contour to highlight the modulation patterns of the fluorescence intensity resulting from the structured illumination. d Standard wide-field and e reconstructed SIM images of NADH in yeast cells. The experiment is independently repeated three times for a–e on different samples. f and g zoomed images of the area delimited by the orange rectangle in d and e, respectively. h Cross-section profiles along the segment [AB] in f and g.
