Is MINFLUX the right method to explore biology at the nanoscale?

Poster presented as part of the Crick BioImage Analysis Symposium

MINFLUX is a promising new development in single-molecule localization microscopy, claiming a resolution of 1-3 nm in living and fixed biological specimens. While MINFLUX can achieve very high localisation precision, quantitative analysis of reported results leads us to dispute the resolution claim and question reliability for imaging sub-100-nm structural features, in its current state.
