Cutting off glucose provision by glucose oxidase (GOx) to famish tumors can be an assistance with chemotherapy to eliminate cancer cells. Co-encapsulation of GOx and chemotherapeutics (doxorubicin) within pH-sensitive metal-organic frameworks (MOFs) could disorder metabolic pathways of cancer cells and generate excessive intracellular reactive oxygen species (ROS), together. To prevent premature leach of GOx from the porous channels of MOFs, polydopamine (PDA) was deposited on the surface of MOFs, which endowed the delivery system with photothermal conversion ability. Our nanoscaled co-delivery system (denoted as DGZPNs) remains stable with low amount of drug leakage under simulated physiological conditions in vitro and internal environment, while they are triggered to release doxorubicin (DOX) and GOx in acid tumor microenvironment and at high temperature for reinforced chemotherapy. NIR laser irradiation also activates superior photothermal conversion efficiency of PDA (36.9 %) to initiate hyperthermia to ablate tumor tissue. After being phagocytized by 4 T1 cells (breast cancer cells), the DGZPNs delivery system showed a superior therapeutic efficacy with a tumor growth inhibition of 88.9 ± 6.6 % under NIR irradiation, which indicated that the starvation-assisted chemo-photothermal therapy prompts the significant advance of synergistic therapy in a parallelly controlled mode.
