Biomimetic intelligent nanoplatform with cascade amplification effect for tumor synergy therapy.

ABSTRACT: Tumor heterogeneity, immune-suppressive microenvironment and the precise killing of tumor cells by drugs are important factors affecting tumor treatment. In this study, we developed environment-responsive drug delivery system (FM@IQ/PST&ZIF-8/DOX) based on ZIF-8 for tumor photothermal/immunotherapy/chemotherapy synergistic therapy. The prepared FM@IQ/PST&ZIF-8/DOX nanoplatfrom not only has highly drug loading capacity for chemotherapeutic drug-doxorubicin, but also erythrocyte membrance modified on their surface can endow their immunity-escaping property and prolong their blood circulation time. More important, the neurotransmitter serotonin was encapsulated on the surface of ZIF-8/DOX by oxidative polymerization, which can effectively avoid the premature leakage of DOX in the blood circul
