The authors retract this article after identifying errors in the fluorescence microscopic images of Figures 3C and 5B. Figure 3C shows microscopic images of an in vitro apoptosis assay for 1, 3, and 5 min. RF exposure on untreated control, functionalized graphene (FG), or transferrin-conjugated FG (TfG) treated cancer cells, respectively. Quantitative cell viability using Alamar-Blue assay (Figure 3B) and an apoptosis study using flow cytometry (Figure 3D) confirmed the enhanced cell death in TfG-treated cells compared to FG. However, errors are present in the microscopy images: In the untreated cell with 5 min RF exposure, the data presented in Figure 3C(iii) was misplaced with that of TfG, 1 min exposure. In the case of the FG sample, 1 min data presented was another micrograph of the same sample at 3 min exposure. Similarly, in Figure 5B, the image of FG, 5 min exposure, was repeated for FG, 3 min. Although the quantitative data were presented correctly, we believe that the misrepresentation of microscopic images warrants retraction of this paper.

撤回“转铁蛋白缀合的可生物降解石墨烯用于肝细胞癌的靶向射频消融”

在确定图3C和5B的荧光显微图像中的错误之后，作者撤回了这篇文章。图3C显示了1、3和5分钟的体外细胞凋亡测定的显微图像。在未经处理的对照，功能化石墨烯（FG）或运铁蛋白偶联的FG（TfG）处理的癌细胞上分别进行RF暴露。使用Alamar-Blue分析（图3B）和使用流式细胞术进行细胞凋亡研究（图3D）的定量细胞活力证实，与FG相比，经TfG处理的细胞死亡增加。但是，显微图像中存在误差：在未经处理的RF暴露5分钟的细胞中，图3C（iii）中显示的数据与TfG暴露1分钟的数据放错了位置。对于FG样品，呈现的1分钟数据是暴露3分钟时同一样品的另一张显微照片。同样，在图5B中，FG图像，曝光5分钟，重复FG，3分钟。尽管定量数据正确显示，但我们认为微观图像的错误表示值得撤回本文。原始文章于2015年1月4日发布，并于2020年12月18日撤回。本文尚未被其他出版物引用。
