66Fe3O4 NPs~11nmTEMa granular shape with a mean size of ˜11 nm
1257Fe3O4 NPs233.7nmTEMThe Fe3O4 nanoparticles were synthesis by the co-precipitation method, and they were around 23 ± 3.7 nm in size as measured by TEM (Figure S2).
1349Fe3O4 NPs91nmTEMThe pristine Fe3O4 NPs exhibit a spherical shape with a uniform diameter in the range of 8–10 nm.

1423Fe3O4 NPs12nmTEMAs shown in Fig. 1(b), irregular Fe3O4 NPs with an average size of 12 nm were observed. For Fe3O4@GO MNCs shown in Fig. 1(c), a large amount of Fe3O4 NPs were observed on sheet like GO. TEM images confirmed the successful assembly of Fe3O4 onto GO to form Fe3O4@GO MNCs.
