“…FeS NSs and graphene oxide), and three-dimensional (3D) metal-organic framework materials (MOFs) (e.g. MIL-53(Fe), MIL-47(V), and ZIF-8) [16][17][18] have been utilized as oxidase-like and peroxidaselike nanozymes in the construction of sensing platforms for the assay of H 2 O 2 , 19,20 glucose, 21,22 glutathione (GSH), 23,24 cancer cells 25,26 and so on. However, the catalytic activity of some nanozymes would be depressed in serum, urine, or living cell samples.…”
