The classification and functions of nanozymes (NZs), including (A) metal and metal-oxide NZs (B) carbon-based NZs (C) single-atom NZs (D) metal organic framework-based NZs, prussian blue NZs. E To facilitate comprehension in this section, NZs are divided into two categories: (1) oxidoreductase family, which consists of enzymes such as nitrate reductase, oxidase, peroxidase, CAT, and superoxide dismutase; and (2) hydrolase family, which comprises the following enzymes: nuclease, esterase, phosphatase, protease, and silicatein [17]
