CAT and neoplasm: On the other hand, tiny Au nanodots act as glucose oxidase (GOx)‐mimic enzyme for tumor starvation through glucose deprivation, which can effectively synergize with redox dyshomeostasis therapy.[40, 41] Importantly, the intrinsic catalase‐like activity of CoFe2O4@Au catalyzes the decomposition of H2O2 into O2, and the resultant hypoxia relief tends to accelerate glucose consumption and promotes SDT process.
