摘 要:Photodynamic therapy(PDT)is a promising cancer treatment that uses photosensitizers(PSs)to generate cytotoxic reactive oxygen species(ROS)under light;but improving its efficacy is crucial for clinical applications.To address this;we propose a smart nanoplatform(P@BAO-DOX)for synergistic chemo-photodynamic therapy;featuring efficient PDT;controllable drug release;and fluorescence imaging guidance.We designed an aggregation-induced emission(AIE)-based PS(BAO)with effective ROS generation and NIR-II fluorescence.Additionally;BAO as a PS and doxorubicin(DOX)as a chemo drug were encapsulated in p H-responsive nanogels(PNA)to obtain P@BAO-DOX nanogels.Upon uptake by tumor cells;the nanogel releases drugs in acidic conditions;leading to cell death.White light irradiation further triggers BAO to produce substantial ROS;enhancing phototoxicity and synergistic chemo-PDT cancer therapy.Thus;P@BAO-DOX nanogels;as a smart nanoplatform;offer precise drug release and efficient ROS generation for imaging-guided chemo-PDT synergistic therapy;showing promise in advancing cancer treatment.
关 键 词:photodynamic therapy aggregation-induced emission pH-responsive nanogels imaging-guided synergistic cancer therapy
