Stimulated emission depletion (STED) nanoscopy of a fluorescent protein-labeled organelle inside a living cell

We demonstrate far-field optical imaging with subdiffraction resolution of the endoplasmic reticulum (ER) in the interior of a living mammalian cell. The diffraction barrier is overcome by applying stimulated emission depletion (STED) on a yellow fluorescent protein tag. Imaging individual structura...
