Correction to: Nature Nanotechnology https://doi.org/10.1038/s41565-024-01681-7, published online 27 May 2024.

In the version of this article originally published online, in the color key to Fig. 4h, “7. CM/NM/Mito i.v. (5 times)” should have been “7. CM/NM/Mito@Cap (5 times)”, and “8. CM/NM/Mito@Cap (5 times)” should have been “8. CM/NM/Mito i.v. (5 times)”. In the second paragraph of the “In vivo therapeutic effects and multi-omics analysis” section, in the text now reading “Echocardiography indicated that although the CM/NM/Mito@Cap (5 times) group and the CM/NM/Mito intravenous (5 times) group were dosed equally, the ejection fraction of the latter was maintained at around 75.3%, and that of the former was 66.2%, indicating that intravenous administration was able to provide better recovery of cardiac function”, the words “latter” and “former” were interchanged. These errors have now been corrected in the HTML and PDF versions of the article.
