Super-resolution microscopy has revolutionised the way we observe biological systems. These methods are now a staple of fluorescence microscopy. Researchers have used super-resolution methods in myriad systems to extract nanoscale spatial information on multiple interacting parts. These methods are continually being extended and reimagined to further push their resolving power and achieve truly single protein resolution. Here, we explore the most recent advances at the frontier of the ‘super-resolution’ limit and what opportunities remain for further improvements in the near future.
