Photodynamic therapy (PDT) is a promising cancer therapy modality due to its intrinsically negligible side effects and treatment resistance. However, the development of the high-efficiency PDT still remains a challenge. Herein, a nanodrug platform PEG-Ce6-PEI@PB combined tumor acidity-induced polyethyleneimine (PEI) cytotoxicity with an oxygen self-supply property is developed for dual-enhanced PDT. The obtained PEG-Ce6-PEI@PB presents suppressed PEI cytotoxicity and chlorin e6 (Ce6) phototoxicity during the bloodstream before becoming active i
