a Schematic illustration of FeIIITA@HA nanoprobe construction. b TEM image of nanoprobes. (The embedded scale bar corresponds to 100 nm). c Hydrodynamic size distribution, d Zeta potential profiles, and e Vis–NIR absorbance spectra of the nanoprobes (0.05 mM of Fe3+). f Temperature variation of aqueous solutions containing nanoprobes with different Fe concentrations under the irradiation of 650 nm laser (1 W·cm−2). g The temperature profile of the nanoprobes aqueous solution with the Fe concentration of 1.00 mM irradiated with 650 nm laser, followed by natural cooling after laser was turned off. h T1-weighted MR images of nanoprobe aqueous solutions (inset), together with the linear regression fitting of the R1 values. i Schematic illustration of the dual-stimuli triggered peroxidase-like activity of nanoprobe. j Fe3+ release kinetics of nanoprobes recorded at different conditions. k Normalized absorbance of MB after adding nanoprobe and H2O2 under different conditions. Inset: Photographs for showing the corresponding visual color changes of MB solutions
