Boosting the antitumor efficacy over a nanoscale porphyrin-based covalent organic polymer via synergistic photodynamic and photothermal therapy.

Porphyrin-based covalent organic polymer nanoparticles were synthesized via a Schiff base reaction at room temperature. The resulting product showed a good photodynamic effect and a high photothermal conversion efficiency (34.88%). Both in vitro and in vivo experiments demonstrated the enhanced antitumor efficacy via synergistic photodynamic and photothermal therapy.
