As traditional cancer treatment methods, photodynamic therapy (PDT) and photothermal (PTT) can eliminate primary tumors, but they cannot inhibit extensive tumor metastasis local recurrence.

Cancer deaths are mainly caused by tumor metastases. However, ablation therapies can only target the primary but not inhibit metastasis. Herein, a multifunctional covalent organic framework (COF)-based nanocomposite is designed for synergetic photo-, chemodynamic- and immunotherapies. Specifically, synthesized COF possesses ability to produce singlet oxygen under 650 nm laser irradiation. After being metallized with FeCl3, p-phenylenediamine polymerized on surface of Fe3+ as oxidant. The...
