Mechanisms of action of Ru(II) polypyridyl complexes in living cells upon light irradiation

The unique photophysical properties of Ru(ii) polypyridyl complexes make them very attractive candidates as photosensitisers in Photodynamic Therapy (PDT). However, to date, there are not many studies exploring in detail the mechanism(s) of action of such compounds in living systems upon light irradiation. This feature article provides an overview of the most in-depth biological studies on such compounds.
