How to cite editorial article?
Since you did not specify the citation style, I chose APA at citethisforme.com, selected journal article and entered the DOI. This is the result:

In-text: ("A matter of scale", 2016)

Bibliography: A matter of scale. (2016). Nature Nanotechnology, 11(9), 733-733. http://dx.doi.org/10.1038/nnano.2016.180

Even so it is an Editorial and has no author, it is still sort of a journal article since it is published in a journal with volume and issue and has a DOI. Therefore, I'd suggest this solution.
