Combined photothermal–photodynamic therapy by indocyanine green loaded polydopamine nanoparticles enhances anti-mammary gland tumor efficacy

We developed novel ICG loaded polydopamine nanoparticles with a hyaluronate outer layer. The nanoparticles exhibited excellent photothermal conversion capacity and efficient singlet oxygen production. IIPH could significantly inhibit the growth of tumors by PTT–PDT.
