The authors wish to make the following corrections to this paper [1]:
- In Figure 2d–f, the TEM images of (d) MSN, (e) MSN-PEI, and (f) MSN-PEI-FA ruler had an error in the unit when enlarging the annotation;
- In Figure 6a, there is something wrong with the mark of concentration unit of Cur;
- The dose of Cur in the experiment was from 10 to 200 µg/mL, but it was mistakenly written as 10–20 µg/mL in the manuscript.
After the publication of this work, we noted the mistake and issued an erratum for correction. The corresponding sentence, Figures 2 and 6a have now been corrected in this erratum.
“The MTT method was used to evaluate the cytotoxicity of MSN-PEI-FA/Cur on colon cancer cells. MSN-PEI-FA/Cur solution of concentrations of 10–200 µg/mL was prepared in PBS”.
The authors would like to apologize for any inconvenience caused to the readers by these changes.
