Violet storm 90 degree7/11/2023 From the dark state, very small populations of (ideally) fluorophore are returned to an emissive state, excited, and detected. STORM and other SMLMs are conceptually similar techniques: the photochemical properties of the fluorophore are exploited to induce a weakly emissive or non-emissive “dark” state. Similar SMLM techniques include Photoactivated Localization Microscopy ( PALM) and Ground State Depletion Individual Molecule Return ( GSDIM), among many others. Pioneered in the laboratory of Xiaowei Zhuang at Harvard University, this technology is available via Nikon’s N-STORM system. Stochastic Optical Reconstruction Microscopy, STORM, is one of a family of Nobel Prize winning super-resolution Single Molecule Localization Microscopies ( SMLM) for the visualization of biological systems with an optical resolution measured in the tens of nanometers (nm) in the x, y, and z directions. Single emitters are recorded over a large number of frames (c-e). (b) Strong laser excitation pushes most fluorophores to a dark state, from which single fluorophores may stochastically return to an emissive state (highlighted in yellow), the centroid position identified (illustrated by black crosses), and finally mapped in a single composite super-resolution reconstruction (f). ![]() (a) Illustration of microtubules in a cell, labeled with fluorophore. Figure 1 - The Basic Principle of STORM Imaging Super-resolution microscopies apply novel approaches to circumvent the diffraction barrier, allowing users to acquire nano-scale information with optical systems. For a detailed discussion of the diffraction barrier in light microscopy, please refer to our article The Diffraction Barrier in Optical Microscopy. This restricts the amount of information that may be captured with standard microscope objectives, generally limiting light microscopy to characterizing micro-scale rather than nano-scale structures. Despite the advantages of traditional fluorescence microscopies, the spatial resolution of such techniques is limited by the diffraction of light ( diffraction barrier). *Do not apply to zoysiagrass just emerging from dormancy.The multiple imaging modes afforded by widefield, confocal, and multiphoton fluorescence microscopies permit noninvasive, temporally resolved imaging of fixed and living cells and tissues with a high level of biochemical specificity.
