As one of the potential alternatives to natural enzymes, vanadium-based nanozymes have received extensive attention in recent years due to their unique physicochemical and optoelectronic properties they exhibit. Their preparation methods have developed relatively maturely. In addition, Due to the multiple valence states of vanadium, vanadium-based nanozymes can mimic various redox enzymes, such as peroxidase, glutathione peroxidase, oxidase, catalase, and superoxide dismutase. Based on the above excellent properties, vanadium-based nanozymes are now finding important applications in disease therapy and biosensing.
