An Amphiphilic Ruthenium Polymetallodrug for Combined Photodynamic Therapy and Photochemotherapy In Vivo

Abstract

An amphiphilic Ru-containing block copolymer is used as a photoactivated polymetallodrug for anticancer phototherapy. The block copolymer self-assembles into nanoparticles, which can accumulate at tumor sites in a mouse model. Red light irradiation of the block copolymer nanoparticles releases anticancer Ru complexes and generates cytotoxic ¹ O₂ , both of which can inhibit tumor growth.
