Long-wavelength triggered iridium(iii) complex nanoparticles for photodynamic therapy against hypoxic cancer

Abstract

A long-wavelength triggered cationic iridium(III) complex, Ir5, and its corresponding nanoparticles with the ability to generate type I and type II reactive oxygen species have been synthesised. The complex targets mitochondria and achieves an excellent photodynamic therapy effect in hypoxic cancer cells.
