“…Apart from sensing target ions, some nanomaterials can also play the specific adsorption function to remove these toxic species simultaneously. Recently, an economical and environmentally friendly nanozyme, chitosan/copper/iron (CS/Cu/Fe), was prepared by Zou et al 77 A portable analytical tube was built by combining CS/Cu/Fe composites with good thermal stability, compatibility and oxidase-mimetic enzyme properties with agarose hydrogels (Figure 8B). Based on the inhibition of TMB-catalyzed oxidation by cysteine and the specific interaction between cysteine and Hg 2+ , Hg 2+ can eventually restore the CS/Cu/Fe oxidase activity, thus allowing a highly sensitive and selective colorimetric detection of Hg 2+ in the analytical tube.…”
