Correction to: Nature Communications https://doi.org/10.1038/s41467-017-00741-y, Article published online 25 September 2017

In the original version of this Article, the penultimate sentence of the Abstract incorrectly read ‘The dose of the contrast agent for effective molecular MRI is only slightly lower than that of ZD2-Cy5.5 (0.5 µmol kg−1) in fluorescence imaging.’ The correct version states ‘higher’ in place of ‘lower’. This error has been corrected in both the PDF and HTML versions of the Article.
