Pushing the Envelope of Super-resolution Live Cell Imaging

Super-resolution (SR) fluorescence microscopy provides the capability of resolving ultra-structure beyond the Abbe limit, but many SR methods encounter practical limitations when imaging nano-scale dynamics in living biological samples, especially for long durations over large fields of view. Structured illumination microscopy (SIM) stands out in the context of live imaging, since many fewer raw images and much lower light levels are required. In addition, its higher efficiency in transmitting spatial frequencies beyond the Abbe limit makes it much less photon demanding than other SR methods. However, it typically offers only a two-fold resolution gain, i.e., around 100 nm for green fluorescent protein. Here I will present the latest development of how to extend SIM resolution into sub-100 nm regime, and simultaneously improve the temporal resolution to hundreds of frames per second; as well as the biology uncovered at this high spatiotemporal resolution level.
