We show that far-field fluorescence nanoscopy by stimulated emission depletion (STED) can be realized with compact off-the-shelf laser diodes, such as those used in laser pointers and DVDs. A spatial resolution of 40-50 nm is attained by pulsing a 660 nm DVD-diode. As already mentioned in Sect. 1.2.1, STED nanoscopy is based on the idea of limiting the ability of molecules to fluoresce in the immediate vicinity of the geometric focus. Since the fluorescence is inhibited by the process of stimulated emission, it is necessary to shape the intensity distribution of the STED light such that it is zero in the geometric focus. The low saturation intensity and high photostability of MitoESq-635 make it ideal for long-term, high-resolution (stimulated emission depletion) STED nanoscopy.

Nanoscopy represented a revolution in fluorescence microscopy but now is a mature technique applied to many branchesofbiology,physics,chemistry,andmaterialsscience. We are currently looking ahead to the next generation of op- Stimulated Emission Depletion (STED) nanoscopy enables multi-color fluorescence imaging at the nanometer scale.

The widely popular class of quantum-dot molecular labels could so far not be utilized as standard fluorescent probes in STED (stimulated emission depletion) nanoscopy. This is because broad quantum-dot excitation spectra extend deeply into the spectral bands used for STED, thus compromising the transient fluorescence silencing required for attaining super-resolution.

The dye is suitable for live cell STED nanoscopy imaging and shows a nontoxic profile which makes it an appropriate candidate for medical Nyckelord: NATURVETENSKAP; NATURAL SCIENCES; Stimulated emission depletion STED microscopy; nanoscopy; multicolor; image analysis; diagnostics; O.
