Correction to: Nature Communications 10.1038/s41467-019-12142-4, published online 27 September 2019
In the version of the article initially published, due to mistakes during figure preparation, there were duplications in Fig. 6c (ICG@Fe/FeO-PPP-FA-0 day, DOX-ICG@Fe/FeO-PPP-FA-18 day, ICG@Fe/FeO-PPP+Laser-12 day, ICG@Fe/FeO-PPP-FA+Laser-6 day) and Fig. 6f (DOX-ICG@Fe/FeO-PPP-FA). The errors were in presentation only and do not affect any conclusions drawn in the study. Due to the age of the paper, the figure cannot be replaced directly; Fig. 6, below, serves to update the article via this amendment.
Fig. 6 Corrected.
