Carrier-free nano-integrated strategy for synergetic cancer anti-angiogenic therapy and phototherapy

Herein, a nano-integrated strategy was used to combine an anti-angiogenic agent sorafenib and a photosensitizer chlorin e6 to form carrier-free multifunctional nanoparticles (SC NPs) for synergetic anti-angiogenic therapy and phototherapy. SC NPs (diameter, ∼152 nm) presented excellent water dispersity and passive targeting ability towards tumor sites
