The authors have advised due to an error at the time of figure assembly, the β-actin of Figure 8D on page 6261 is incorrect and is a duplication of Figure 8C. The correct Figure 8 is shown below.

Effects of Re-CDs on caspase-3 expression related to apoptosis of cancer cells.
Notes: (A) Western blot analysis of the expression of apoptosis protein caspase-3 in A375 cells. (B) The relative gray intensity (vs internal reference) of caspase-3 with different concentrations of Re-CDs in A375 cells. (C) Western blot analysis of the expression of apoptosis protein caspase-3 in MCF-7. (D) Western blot analysis of the expression of apoptosis protein caspase-3 in HepG-2. (E) The relative gray intensity (vs internal reference) of caspase-3 with different concentrations of Re-CDs in MCF-7 and HepG-2 cells. Data in histogram are represented as mean±SD (*P<0.05). Decrease in caspase-3 and the increasing expression of cleaved caspase-3 indicate the apoptosis of A375 cancer cells. While in MCF-7 and HepG-2, we can also observe the decreased expression of caspase-3.
Abbreviations: A375, malignant melanoma cell line; Re-CDs, Re-based carbon dots.
