Publisher Correction: A note on the Lena image

    Correction to: Nature Nanotechnology, published online 6 December 2018.

    In the version of this Editorial originally published, the sentence “Like the Lena image, all these alternatives are in the public domain” was incorrect; it should have said that the alternatives “are widely available”. This has now been corrected in the online versions of the Editorial.
