Correction: Fe-Au Nanoparticle-Coupling for Ultrasensitive Detections of Circulating Tumor DNA (Advanced Materials, (2018), 30, 31, (1801690), 10.1002/adma.201801690)

In Figure S8 in the Supporting Information of the originally published article, three incorrect H&E and immunohistochemical staining images (row 3, column 4; row 5, column 6; and row 6, column 6) were included due to mistakes in naming and storing the image files, and these are hereby updated. All the relevant experiments have been reperformed to verify the results presented in the original experiments, as shown in the updated Figure S8 here. The original Figure S8 should be substituted with the following revised figure. S8 Figure (Figure presented.) a) H&E staining microphotos (200 ×) of heart, liver, spleen, lung, and kidney at 0, 7, 14, 28, and 42 days after inoculation of tumor cells. Scale bars: 200 µm. b) Immunohistochemical staining analyses of original tumors for MMP9 at 0, 7, 14, 28 and 42 days after inoculation of tumor cells. Scale bars: 100 µm.
