We, the Editors and Publisher of International Journal of Nanomedicine, have retracted the following article.

Following publication, the authors raised concerns about the duplication of images within the article. Specifically,

• The images for Figure 4C and 4F have been duplicated, as have the images for Figure 4D and 4E.
• The images for Figure 6A and 6B have been duplicated, as have the images for Figure 6C and 6D.

It was noted that some images for Figures 2 and 10 may have duplicated regions, however, this was caused by an error during the publication process.

When approached for an explanation, the authors were cooperative but wereg unable to provide an adequate explanation for the duplicated images and not all the original data for the study was available. As verifying the validity of published work is core to the integrity of the scholarly record, we are therefore retracting the article and the authors agreed with this decision.

We have been informed in our decision-making by our editorial policies and COPE guidelines.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
