(a) UV–vis absorption of Fe3O4@Au (black curve), Fe3O4@Au-HPG (red curve), pure glucose (blue curve) and Fe3O4@Au-HPG-Glc (pink curve); (b) FTIR spectra of the Fe3O4@Au (black curve), Fe3O4@Au-HPG (red curve) and Fe3O4@Au-HPG-Glc nanoprobes (blue curve). (c) Magnetization loops of the Fe3O4 and Fe3O4@Au-PG-Glc nanoprobes, measured at 300 K. (d) Linear fitting of 1/T2 for Fe3O4@Au-HPG-Glc with Fe concentrations of 0.016, 0.032, 0.0625, 0.125, 0.25, 0.5 and 1 mM.
