Super-resolution microscopy: a brief history and new avenues

<p>A brief history of far-field SRM. (a) Timelines highlighting crucial milestones in the development of SRM techniques (top) and the corresponding introduction of commercial turn-key super-resolution systems (bottom). For each SRM technique, the corresponding authors of the subsequent publication have been listed. (c) The number of publications extracted from the Web of Science database. (d) Correlation between the approximate purchase costs and the nominal lateral (xy) resolution or localization precision (SMLM-based systems) achievable under ideal conditions, for commercial and open-source microscopy systems, respectively.</p>
