A covalent organic framework-based nanoreactor for enhanced photothermal therapy via inhibiting intracellular heat defense systems

Herein, we report an indocyanine green (ICG)-decorated and glucose oxidase (GOx)-loaded nanoscale composite COF material via a stepwise post-synthetic modification. The obtained GOx@COF-ICG can achieve synergistic inhibition of intracellular heat defense systems through starvation therapy to enhance photothermal therapy of tumors.
