An ATP-responsive ZIF-based NIR fluorescence nanosystem for enhanced chemo-photodynamic therapy of tumors.

The combination of chemotherapy and photodynamic therapy holds immense potential for achieving synergistic anti-tumor efficacy. However, challenges such as poor stability and premature drug release prior to reaching tumor sites impede the widespread application of this synergistic therapeutic approach. In this study, a novel ATP-responsive NIR fluorescence nanosystem (CDZ) for imaging-guided chemotherapy and PDT has been developed.

ATP-responsive copper(II)-doped ZIF-nanoparticles for synergistic cancer therapy: combining cuproptosis and chemo/chemodynamic therapy.

Cancer, a pressing global health challenge, is characterized by its rapid onset and high mortality rates. Conventional treatment methods prove insufficient in achieving the desired therapeutic outcomes, underscoring the critical need to identify an effective and safe approach for cancer treatment. In this study, a copper-doped nanoparticle known as Cu-DOX@ZIF-90 is designed by incorporating copper(II) (Cu(II)) and encapsulating doxorubicin (DOX) within ZIF-90.
