SOFISM (IMAGE) University of Warsaw, Faculty of Physics Caption Image of microtubules in a fixed cell sample. A 3 microns x 3 microns confocal scan of microtubules in a fixed 3T3 cell labelled with quantum dots analyzed in two ways. Upper left: image scanning microscopy (ISM), lower right: super-resolution optical fluctuation image scanning microscopy (SOFISM) after Fourier-reweighting. (Source: UW Physics, A. Makowski).
