Correction: Copper nanocrystalline-doped folic acid-based super carbon dots for an enhanced antitumor effect in response to tumor microenvironment stimuli

Abstract

Correction for ‘Copper nanocrystalline-doped folic acid-based super carbon dots for an enhanced antitumor effect in response to tumor microenvironment stimuli’ by Qing Xia et al., J. Mater. Chem. B, 2022, 10, 8046–8057, https://doi.org/10.1039/D2TB01363K.

In the version of this article originally published, the ‘Liver/FA-CDs@Cu^x’ tissue image in Fig. 5e was presented incorrectly. The correct image appears below:

Fig. 5 (e) H&E stained images of tumor sections, heart, liver, spleen, lung and kidney collected from different groups of mice after 14 days of treatment.

 

In the electronic supplementary information (ESI) of the original publication of this paper, an image of the stained cells in Fig. S6b was incorrectly presented. The correct image appears below:

Fig. S6 (a) MTT assay to detect the toxicity of FA-CDs@Cu^x on 4T1 cells; (b) Live-dead cell staining of 4T1 cells.

 

In the ESI of the original publication of this paper, two images of the in vivo fluorescence imaging in Fig. S7 were incorrectly presented and organized. For the sake of caution, the authors re-did the live imaging experiment and got some new images. The new experimental results are in agreement with the conclusions in the main article. The correct Fig. S7 appears below:

Fig. S7 In vivo fluorescence imaging of CDs and FA-CDs at different intervals (0, 2, 4, 8, 12 h).

 

An independent expert has viewed the corrected figures and confirmed that they are consistent with the discussions and conclusions presented.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
