“…Natural polyphenols with abundant phenolic hydroxyl groups have attracted extensive attention in constructing multienzyme-like platforms due to their antioxidative activities, exceptional biocompatibility, metal chelating properties, and universal adherent affinity. − Especially, polyphenols could coordinate with multiple metal ions to form metal–phenolic networks (MPNs) to integrate the advantages of the two components for the rational design of diverse MPNs-based materials for biomedical applications. ,− Meanwhile, benefiting from their numerous properties, we have demonstrated that the MPNs are suitable as building blocks for constructing multienzyme-like nanomaterials with tunable enzyme-mimetic activities. , …”

Green synthesis of multienzyme-like materials with low energy consumption and high economic added value remains challenging; thus, exploring economical and environmentally friendly strategies to develop multienzyme-like platforms is of great significance. Herein, a biomass (polyphenols)-based strategy to develop cost-efficient and high-performance platforms (manganese-tannic acid enzyme mimics, TAnc-Mn x -y platforms) with multienzyme-mimetic capacities is developed via the mineralization of metal−phenolic networks (MPNs) in an aqueous solution. This green synthesis strategy requires only water as a solvent and polyphenols and metal ions as feedstocks and requires no additional energy supply, making it simple and cheap. The mineralization process realizes the generation of MnO x -TA petals, which endows TAnc-Mn x -y with the flower-like surface, therefore enhancing the surface area and pore size. Benefiting from the flower-like surface and MnO x active sites, TAnc-Mn x -y with enhanced surface area and pore sizes displays exceptional oxidase (OXD)-, peroxidase (POD)-, and catalase (CAT)-mimetic activities. Excitingly, TAnc-Mn x -y could realize fast L-cysteine detection owing to their excellent OXD-mimetic activity. Colorimetric studies of TAnc-Mn x -y have shown a relatively wide detection range (8.26−90.86 μM), a fast detection speed (2 min), and a significantly low detection limit (2.28 μM) for L-cysteine detection. Moreover, TAnc-Mn x -y displays remarkable resistance to harsh environments and excellent selectivity among the other amino acids. In addition, the blood experiments also confirm the excellent biocompatibility of TAnc-Mn x -y. We believe that this study not only overcomes the current limitation of the synthesis for multienzyme-like nanoplatforms but also provides interesting insights for developing sensitive and selective methods for L-cysteine detection.
