Iron-based nanozymes are enzymatically active nanomaterials containing a certain proportion of iron. Since the ferromagnetic (Fe3O4) nanoparticles were firstly reported to exert enzyme-like activity in 2007, iron-based nanozymes have attracted widespread attention from researchers due to their good enzymatic activity, low cost, high stability and easy storage. Iron in iron-based nanozymes participates in many life activities as an important metal element of the human body. Therefore, iron-based nanozymes also exhibit other significant advantages, such as low toxicity, low immunogenicity, and high biodegradability used in vivo. Due to their excellent properties, iron-based nanozymes have broad prospects in future.
