Abstract
Overcoming Abbe's diffraction limit has been a challenging task and one of great interest for biological investigations. The emergence of fluorescence nanoscopy circumvents the diffraction barrier with nearly limitless power for optical microscopy, which enables investigations of the microscopic world in the 1-100 nm range. Proposed variants, such as expansion microscopy (ExM), stimulated emission depletion microscopy (STED), and Airyscan, are innovative in three aspects: sampling, illumination, and detection. These techniques show increasing strength in bioimaging subcellular structures. In this Perspective, we highlight advances in and prospects of fluorescence nanoscopy.
