Correction to: Nature Nanotechnology https://doi.org/10.1038/s41565-019-0431-0, published online 2 April 2019.

In the version of this Research Highlight originally published, the text ‘Now, Nishioka et al. have shown that carefully designed gemini amphiphiles can also form micelles’ should have read ‘Now, Nishioka et al. have shown that aromatic gemini amphiphiles can form monodisperse micelles’. This has now been corrected.
