Corrigendum to “PEI-PEG-Coated Mesoporous Silica Nanoparticles Enhance the Antitumor Activity of Tanshinone IIA and Serve as a Gene Transfer Vector”

---

In the article titled “PEI-PEG-Coated Mesoporous Silica Nanoparticles Enhance the Antitumor Activity of Tanshinone IIA and Serve as a Gene Transfer Vector” [1], there are errors in the mass ratios in Figure 4(b) that should be corrected to 1:5, 1:10, 1:20, 1:40, 1:60, 1:80, and 1:100. In addition, the electrophoresis images in Figures 4(c) and 4(d) are in the wrong order.

The authors explained that these errors were inadvertently introduced during figure assembly. The corrected Figure 4 is as follows.
