Stimulated Emission Depletion microscopy, or STED nanoscopy, is a technique that uses the non-linear de-excitation of fluorescent dyes to overcome the resolution limit imposed by diffraction encountered with standard confocal laser scanning microscopes and conventional far-field optical microscopes.
Compared to traditional confocal microscopy, STED offers exceptional improvements in resolution allowing visualization of cellular events at unprecedented levels.
