Heterometallic ruthenium–osmium complexes: dual photodynamic and photothermal therapy for melanoma and drug-resistant lung tumourin vivo

A hetero-dinuclear Ru–Os complex can entirely eradicate PDT-resistant melanoma and cisplatin-resistant non-small cell lung tumors by dual PDT/PTT under an 808 nm low-power laser. It also has low hepatorenal toxicity and low metal residue in mice.
