CAT and neoplasm: Nanozymes, characterized by theiraffordability, robustness, andenzyme-mimicking characteristics, have effectively initiated catalyticprocesses within tumor cells.230,231 The nanozymes currentlyemployed in medical applications primarily mimic oxidoreductase enzymes.These nanozymes can be broadly categorized into four principal typesbased on their distinct catalytic functions: (i) peroxidase (POD),(ii) oxidase (OXD), (iii) superoxide dismutase (SOD), and (iv) catalase(CAT).231
