Nanozymes can be broadly classified based on their composition and the type of enzymatic activity they mimic. Some common types include:
1. Metal Oxide Nanozymes: These mimic various oxidase and peroxidase enzymes. For example, iron oxide nanoparticles can act like peroxidase, catalyzing the breakdown of hydrogen peroxide. 2. Metal Nanoparticles: Gold nanoparticles and silver nanoparticles can mimic a range of enzymes, including oxidases and reductases. 3. Carbon-based Nanozymes: Graphene and carbon nanotubes can exhibit peroxidase-like activity and are used in biosensing and pollutant degradation. 4. Hybrid Nanozymes: Combinations of different materials to create multifunctional nanozymes, enhancing catalytic activities and broadening application scope.
