Two in one: A novel strategy for efficiently coencapsulating both arsenic- and platinum-based drugs into 100 nm-scale liposomes (NBs) relies on the formation of PtII–AsIII adducts. This co-loaded system presents a robust platform for further modification with targeting ligands and affords a method of improving the therapeutic efficacy of anticancer agents.
