Polymeric nanoparticles that can stably load anticancer drugs and release them in response to a specific trigger such as glutathione are of great interest in cancer therapy. In the present study, dendrimer-encapsulated gold nanoparticles (DEGNPs) were synthesized and used as carriers of thiolated anticancer drugs. Thiol-containing drugs such as captopril and 6-mercaptopurine loaded within DEGNPs showed an "Off-On" release behavior in the presence of thiol-reducing agents such as glutathione and…
