    摘要: Modified metal-organic framework (MOFs) are described that have surfaces with enhanced ability to coordinatively bond to or electrostatically interact with therapeutic agents, such as nucleic acids and small molecules and proteins with phosphate or carboxylate groups. Methods of providing the modified MOFs are described that include replacing strongly coordinating metal oxo cluster capping groups with weakly coordinating capping groups and/or incorporating organic bridging ligands with electron-withdrawing groups. MOFs with surface attached therapeutic agents (e.g., immunotherapeutic agents) prepared from the modified MOFs are also described, along with methods of using the MOFs as to treat cancer, e.g., via radiotherapy-radiodynamic therapy (RT-RDT), either with or without the co-administration of another therapeutic agent, such as a chemotherapeutic agent or an immunomodulator. Thus, the described methods can involve cancer immunotherapy and in situ cancer vaccination.
