Combination cancer immunotherapy based on electromagnetic energy and shows potent anti-cancer efficacy. However, as a factor that mediates tumor metastasis immune suppression, the impact of exosomes therapy under stimulation remains unclear. Herein, findings indicate sonodynamic (SDT) increases serum exosome levels by inducing apoptotic loosening extracellular matrix, promoting lung metastasis. To address this problem, an exosome-inhibiting polymeric sonosensitizer (EIPS) selectively inhibiting generation in response to biomarker is synthesized. EIPS consists semiconducting polymer backbone capable SDT poly(ethylene glycol) layer conjugated with tumor-specific enzyme-responsive inhibitor prodrug.
