Three in One: Viscosity-Sensitive Ruthenium(II) Complexes for Photodynamic Anticancer by Activating Pyroptosis with Self-Evaluation Therapeutic Efficacy and Two-Photon Imaging

exhibits superior PDT efficacy and provides real-time feedback on treatment response via its self-reporting luminescence characteristics. This work provides new insights into the design and implementation of multifunctional photosensitizers for tumor cell pyroptosis with real-time therapeutic monitoring and two-photon imaging.
