Cancer-Targeting Functionalization of Selenium-Containing Ruthenium Conjugate with Tumor Microenvironment-Responsive Property to Enhance Theranostic Effects
A mutifunctional ruthenium‐based conjugate Ru‐BSe was designed and synthesized. The Ru complex with favorable bioimaging function was covalently linked with a cancer‐targeted molecule that could be effectively internalized by the tumor to realize enhancedtheranosticeffects. The pH‐response of the Ru conjugate in tumor acidic microenvironment causes ligand substitution and release of therapeutic complex
We have described the rational design of selenium-containing ruthenium complexes and their use as cancer radiosensitizers through regulating ROS-mediated pathways.

Rational design of NIR-emitting iridium(<scp>iii</scp>) complexes for multimodal phosphorescence imaging of mitochondria under two-photon excitation
A series of NIR-emitting iridium(III) complexes were developed for multimodal phosphorescence imaging (NIR imaging, phosphorescence lifetime imaging and time-gated imaging) of mitochondria in living cells, 3D multicellular spheroids (MTCCs) and hippocampus slice under two-photon excitation.
In the present study, four mitochondria‐specific and two‐photon phosphorescence iridium(III) complexes, Ir1–Ir4, were developed for mitochondria imaging in hypoxic tumor cells. The iridium(III) complex has two anthraquinone groups that are hypoxia‐sensitive moieties. The phosphorescence of the iridium(III) complex was quenched by the functions of the intramolecular quinone unit, and it was restored
