Phototherapeutic activity of polypyridyl ruthenium( ii ) complexes through synergistic action of nitric oxide and singlet oxygen

experiments indicated that Ru2 elevated the levels of ROS and NO in HeLa cells when exposed to light, resulting in mitochondrial impairment and caspase-mediated cell death. Overall, Ru2 proves to be a potent phototherapeutic compound, capable of producing ROS and NO, thus providing precision in cancer phototherapy.
