Sub-diffraction-limit imaging by stochastic optical reconstruction microscopy (STORM)

Nat Methods. 2006 Oct;3(10):793-5. doi: 10.1038/nmeth929. Epub 2006 Aug 9.


We have developed a high-resolution fluorescence microscopy method based on high-accuracy localization of photoswitchable fluorophores. In each imaging cycle, only a fraction of the fluorophores were turned on, allowing their positions to be determined with nanometer accuracy. The fluorophore positions obtained from a series of imaging cycles were used to reconstruct the overall image. We demonstrated an imaging resolution of 20 nm. This technique can, in principle, reach molecular-scale resolution.
