designed a tumor‐targeted cascade bioreactor mem@catalase@GOx@PCN‐224 (mCGP) by the encapsulation of glucose oxidase (GOx) and catalase in tumor cell membrane‐camouflaged PCN‐224 NMOFs for synergistic starvation and PDT.[52b] It was found that mCGP could facilitate microenvironmental oxygenation by catalyzing endogenous H2O2 to generate O2 by catalase, which would subsequently accelerate the consumption of intracellular glucose by GOx and increase the generation of 1O2 under 660 nm irradiation. The gene discussed is CAT; the disease is neoplasm.
