Super-resolution microscopy by single-molecule photoactivation or photoswitching and position de-termination (localization microscopy) has the potential to fundamentally revolutionize our under-standing of how cellular function is encoded at the molecular level. Among all powerful high-resolution imaging techniques introduced in recent years localization microscopy excels at it delivers single-molecule information about the distribution and, adequate controls presupposed, even abso-lute numbers of proteins present in subcellular compartments. This provides insights into biological systems at a level we are used to think about and model biological interactions. We briefly introduce basic requirements of localization microscopy, its potential use for quantitative molecular imaging, and discuss present obstacles and ways to bypass them. We demonstrate the advantageous use of dSTORM for quantitative imaging of synaptic proteins, the study of plasma membrane organization, and the molecular architecture of multiprotein complexes. Finally, we outline how dSTORM can be used advantageously to improve next generation medical therapies.
