Bimetallic metal-organic frameworks for tumor inhibition via combined photothermal-immunotherapy.

Herein, we report the design of therapeutic nanoparticles by encapsulating photosensitizers and aluminum ions into metal-organic frameworks. The nanoparticles could significantly inhibit the growth of primary and rechallenged tumors by a combination of photothermal therapy and immunotherapy. This work offers a promising strategy to design an immunologic nanoplatform for "cold" tumor therapy.
