Popis: Recent developments in stimulated emission depletion (STED) microscopy achieved nanometer scale resolution and showed great potential in live cell imaging. Yet, STED nanoscopy techniques are based on single point-­‐scanning. This constitutes a drawback for wide field imaging, since the gain in spatial resolution requires dense pixelation and hence long recording times. Here we achieve massive parallelization of STED nanoscopy using wide-­‐field excitation together with well-­‐designed optical lattices for depletion and a fast camera for detection. Acquisition of large field of view super-­‐resolved images requires scanning over a single unit cell of the optical lattice which can be as small as 290 nm*290nm. Interference STED (In-­‐STED) images of 2.9 μm* 2.9 μm with resolution down to 70 nm are obtained at 12.5 frames per second. The development of this technique opens many prospects for fast wide-­‐field nanoscopy.
