A Study of Nanozymes

Nanomaterials with enzyme-like properties (called nanozymes) have attracted significant research interest due to their simple preparation, storage, as well as the low-cost compared with natural enzymes. We started to study nanozymes 10 years ago, several new peroxidase-like mimics with high catalytic activity have been prepared.

Here, a few examples of novel nanozymes proposed from our laboratory very recently will be reported. NiPd hNPs synthesized by galvanic replacement method exhibited triple-enzyme mimetic activities, such as oxidase-like activity, peroxidase-like activity and catalase -like activity. One-pot synthesis of Fe3O4 NPs on 3D porous graphene nanocomposites by using hemin as the iron source has been successfully fabricated,which showed enhanced nanozyme activity and used for glucose determination. GOx@ZIF-8(NiPd) nanoflower exhibiting tandem catalysis for both nanozymes and natural enzymes has been firstly proposed. Based on the GOx@ZIF-8(NiPd) nanoflower, colorimetric determination of glucose could be combined into one step. The nanoflower could also be used for electrochemical determination of glucose based on the good electrocatalytic activity towards ORR.

As a whole, nanomaterials with enzyme-like characteristics will play the main role as the next-generation of artificial enzymes.
