996Boosted peroxidase-like activity of metal-organic framework nanoparticles with single atom Fe (Ⅲ) sites at low substrate concentrationhttps://doi.org/10.1016/j.aca.2021.338299MOFHere, we report a peroxidase-like SAzyme through the post-modification route based on hydrophilic defective metal-organic frameworks. Hydrochloric acid (HCl) is employed as ligand modulator to fabricate defective NH2-UiO-66 nanoparticles (HCl–NH2-UiO-66 NPs).
